Question

The prism has a volume of 120 cm3.

What would the volume of the prism be if each dimension were halved? 60?

Answer 1

Answer 2

volume of prism = area of base time height

soppose a prism with base a square and height equal length of square side
120 = a*a*a

so than eache dimensions was halved

120 = (a/2)*(a/2)*(a/2)

120 = (a/2)^3

120 = a^3 /8

a^3 = 120/8 = 15

a= cuberoot(15)

so than a side length and the height will be equal cuberoot 15

so than the volume will be (cuberoot15)^3 = 15 cm^3

hope this is understandably easy

good luck

bye bye
