Question

Can you explain 2 methods for finding volume of a prism?

Answer 1

Write down the formula for finding the volume of a triangular prism. The formula is simply V = 1/2 x length x width x height. However, we'll be taking this formula apart further to use the formula V = area of base x height. You can find the area of the base by using the formula for finding the area of a triangle -- multiplying 1/2 by the length and width of the base.

Answer 2

Find the area of the base face. To calculate the volume of a triangular prism, you need to first find the area of the triangular base. Find the area of the base of the prism by multiplying 1/2 times the base of the triangle times its height.[1]
Ex: If the height of the triangular base is 5 cm and the base of the triangular prism is 4 cm, then the area of the base is 1/2 x 5 cm x 4 cm, which is 10 cm2.

Answer 3

Write down the formula for finding the volume of a cube. The formula is simply V = side3. A cube is a prism that happens to have three equal sides.[2
