Question

A triangular prism has a volume of 64 yd3. If each dimension of the prism is reduced by half, what is the new volume of the prism?

32 yd3

16 yd3

128 yd3

8 yd3

Answer 1

You need to use scale factors.
Since all the dimensions are reduced by half, the linear scale factor (LSF) is 1/2.
We want the change in volume, so calculate the volume scale factor (VSF) which is
VSF = LSF^3 = 1/8
Thus new volume = 64*VSF
