Question

I need a full explanation for this problem. I don’t know how to do it

Answer 1

• 3861 cm³

Explanation:

Consider this solid as combination of two prisms, one with recrangular base and another with trapezoid base.

Find the area of bases

Rectangle

• A = lw = 8*17 = 136 cm²

Trapezoid

• A = (1/2)(17 + 6)(22 - 8) =(1/2)(23)(14) = 161 cm²

Find the total base area

• B = 136 + 161 = 297 cm²

Find the volume

• V = Bh
• V = 297*13 = 3861 cm³
