Answer 1

Answer: B. 111.36

Volume of a rectangular prism is:

V = LWH

Divide this shape into two rectangular prisms, the top vertical one and the bottom horizontal one.

Lets start with the top one:

L = 4
W = 2.4
H = 8

V = (4)(2.4)(8)

V = 76.8 units cubed

Now lets find the bottom one:

L = 2.4
W = 2.4
H = 6

V = (2.4)(2.4)(6)

V = 34.56 units cubed

Now add these two volumes for the total volume:

76.8 + 34.56 = 111.36 units cubed
