Question

Suppose you take the small prism and stack it on top of the larger prism. What will be the volume of the composite figure

Answer 1

You didn't provide a picture, but if your problem is like the one in my workbook, I might be able to help.

Find the volume of the first figure, then find the volume of the second figure, then add them together.

V=lwh

V(1)=(15)(12)(6)

= 1,080in^3

V(2)=(12)(6)(6)

= 432in^3

--------------------------------------------

1,080+432= 1,512 in^3

--------------------------------------------

Your answer should be 1,512
