Question

Please answer all three​

Answer 1

Answer:

Rectangular Pyramid volume = 84 ft^3
Rectangular Prism volume = 840 ft^3
Total volume = 924 ft^3

Explanation:

Rectangular pyramid volume = 1/3 bh
Rectangular pyramid volume = 1/3 (84)(3)
Rectangular pyramid volume = 1/3 252
Rectangular pyramid volume = 84

Rectangular prism volume = l • w • h
Rectangular prism volume = 12 • 10 • 7
Rectangular prism volume = 840

840 + 84 = the total volume of the composite

The total volume of the composite = 924

Answer 2

Rectangular pyramid volume: 120 ft³

Rectangular prism volume: 840 ft³

Total volume of the composite figure: 120+840 = 960 ft³
