Question

Find the volume of the triangular pyramid to the nearest whole number. the base is 12 the height is 17. and the apothem is 10 inches they are all inches.

Answer 1

Answer:

340 cubic inch

Step-by-step explanation:

We are given the base, height and apothem of a triangular prism.

Apothem means the height of the base of the prism

Base=12 inches

Height=17 inches

Apothem=10 inches

Volume of triangular prism=(Area of Base x Height) ÷ 3

Area of base= (Base×Apothem)÷2=12×10÷2

                                                        = 60 sq. in.

Volume=(60×17)÷3

            = 340 cubic inch.

Answer 2

So the equation is (base *height)/2 
In this case: 12*17= 204 
204/2=102 in^3
