Question

A rectangular prism is truncated removing 30% of its height. The original height of the prism was 100 cm and it has a length of 6 cm and a width of 12 cm. What is the volume of the truncated prism?

Answer 1

The volume of a rectangular prism is length*width*height, correct? If so,

V = l*w*h.

V(original) = .06*.12*1.0

V(new) should be .06*.12*(?).

(?) = .7(1.0) (because a 30 percent decrease will be 70% of the previous value, i.e. that value times .7)

V(new) = .06*.12*.70 = ???

There's your equation. Got it now?

Answer 2

Yeah thanks!

Answer 3

No problem dude.
