Answer :

MHANIFAGO

Answer:

  • 3861 cm³

Step-by-step 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
