Question

A pyramid with triangular base is stack on top of a triangular prism. the pyramid shares a triangular base with the prism. the triangular base has a height of 2 and a base length of 4.4. the height of the prism is 5. the height of the pyramid is 3.9. which expression represents the volume of the composite figure? (2)(4.4)(5) (2)(4.4)(3.9) (2)(4.4)(5) – (2)(4.4)(3.9) one-half(2)(4.4)(5) – one-third (one-half)(2)(4.4)(3.9) one-half(2)(4.4)(5) one-third (one-half)(2)(4.4)(3.9)

Answer 1

An expression which represents the volume of the composite figure is: D. one-half(2)(4.4)(5) + one-third (one-half)(2)(4.4)(3.9).

How to calculate the volume of a triangular prism?

Mathematically, the volume of a triangular prism is calculated by using this formula:

Volume = base area × length of the prism.

In this scenario, the triangular prism would be cut into half while the triangular pyramid is divided by 3, and then cut into half.

Lastly, the equations derived would be added to get the volume of the composite figure as follows:

Volume = 1/2 × [(2)(4.4)(5)] + 1/3 × [(1/2) × (2)(4.4)(3.9)]
