find the volume of A trapezoid prism of height 4Km.The parallel sides of the base have length 8km and 5km. The other sides of the base are 2km each. The trapezoid altitude is 1.5km.

Respuesta :

Answer:

Volume of prism = 39 km cubed

Step-by-step explanation:

IMPORTANT FORMULA: Volume of any prism = Area of base * Height

In this case, the area of the base means the area of the trapezoid.

Area of trapezoid = base1+base2/2  * height

Area of trapezoid = 8+5/2  * 1.5

Area of trapezoid = 13/2  * 1.5 = 9.75

We already know that the height of the trapezoidal prism is 4 kilometers.

So, we have all of the values that are needed to correctly fill in the formula.

Volume of the prism = 9.75 * 4 = 39
