Answer/Step-by-step explanation:
Decompose each shape, find the volume of each cuboid, and add both volumes you get together.
Recall: volume of cuboid = L*W*H
4. Volume of cuboid 1: L*W*H = 12*10*4 = 480 ft³
Volume of cuboid 2: L*W*H = 12*3*5 = 180 ft³
Volume of the shape = 480 + 180 = 660 in.³
5. Volume of cuboid 1: L*W*H = 11*2*5 = 110 yd³
Volume of cuboid 2: L*W*H = 10*4*2 = 80 yd³
Volume of the shape = 110 + 80 = 190 yd³
6. Volume of cuboid 1: L*W*H = 8*3*2 = 48 in.³
Volume of cuboid 2: L*W*H = 14*2*3 = 84 in.³
Volume of the shape = 48 + 84 = 132 in.³
7. Volume of cuboid 1: L*W*H = 5*3*2 = 30 yd³
Volume of cuboid 2: L*W*H = 6*2*5 = 60 yd³
Volume of the shape = 30 + 60 = 90 yd³
8. Volume of cuboid 1: L*W*H = 12*2*18 = 432 in.³
Volume of cuboid 2: L*W*H = 18*5*6 = 540 in.³
Volume of the shape = 432 + 540 = 972 in.³
9. Volume of cuboid 1: L*W*H = 13*11*4 = 572 ft³
Volume of cuboid 2: L*W*H = 13*6*7 = 546 ft³
Volume of the shape = 572 + 546 = 1,118 ft³
