The equation for finding the volume of a triangular prism is: ½ × b × h × l = Volume. This means that the equation for the 1st problem would've been: ½ × 7 × 3 × 4 = 42. And you probably just forgot to multiply your equation by ½: 7 × 3 × 4 = 84.
Volume of a cube is the total cubic units occupied by it, in a three-dimensional space. A cube is a 3d-shape, that has six faces, twelve edges and eight vertices. Hence, the volume of a cube is the space enclosed by its six faces. Unlike, 2d shapes, it has additional dimensions apart from length and width, which is called height or thickness. This means that each of the cube's six faces is a square. The total surface area is therefore six times the area of one face. Or as a formula: surface area. =. 6. s. 2. Where s is the length of any edge of the cube. The surface-area-to-volume ratio has physical dimension inverse length (L −1) and is therefore expressed in units of inverse metre (m -1) or its prefixed unit multiples and submultiples. As an example, a cube with sides of length 1 cm will have a surface area of 6 cm 2 and a volume of 1 cm 3. The surface to volume ratio for this cube is thus.
The cube is a special case of many classifications of shapes in geometry, including being a square parallelepiped, an equilateral cuboid, and a right rhombohedron. Below is the equation for calculating the volume of a cube: volume = a 3 where a is the edge length of the cube
An edge of a variable cube is increasing at the rate of 3 cm/s. How fast is the volume of cube increasing when the edge is 10 cm long? View Solution. Q2. The edge of a cube is increasing at the rate of 7 c m / s e c. How fast is the volume of the cube increasing when the edge is 10 c m long?

If you need to convert to cubic feet from inches: divide the final number (i.e. the total you get after multiplying the three dimensions together) by 1728. If you need to convert to cubic feet from meters/metres: multiply your final number by 35.31. If you need to convert to cubic feet from yards: multiply your final number by 27.

You need to rearrange the formula to: volume = mass / density. Whenever you use this formula, remember to be concise with units. For example, if you input mass in pounds, and volume in gallons you will get density in pounds per gallon. In our volume to mass calculator, you can input values in any unit you want - our calculator will convert

Transcript. Ex 6.1, 2 The volume of a cube is increasing at the rate of 8 cm3/s. How fast is the surface area increasing when the length of an edge is 12 cm?Let 𝒙 be length of side V be Volume t be time per second We know that Volume of cube = (Side)3 V = 𝒙𝟑 Given that Volume of cube is increasing at rate of 8 cm3/sec.

How many cubical boxes of dimensions 3 cm x 3 cm x 3 cm can be packed in a large cubical case of length 15 cm. Solution. To find the number of boxes that can be packed in the case, divide the case's volume by the volume of the box. Volume of each box = (3 x 3 x 3) cm 3 = 27 cm 3. Volume of the cubical case = (15 x 15 x 15) cm 3 = 3375 cm 3 The formula for finding the volume of cube is: Volume = side x side x side. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object. An object with a larger volume would occupy more space. m2Ta.
