Answer:

86.9 cm^3

Step-by-step explanation:

You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.

2(5.3x2)=21.2

2(4.5x2)=18

2(4.5x5.3)=47.7

You then add the values together...

21.2+18+47.7=86.9

Because there are four faces that have the measurement of 5.3*4.5, you do 4(5.3*4.5)

Because there are two faces have the measurement of 4.5*2, you do 2(4.5*2)

Which gives you an expression of 2(4.5*2)+4*(5.3*4.5)

Which is 113.4
