Question

a manufacturer uses a mold to make a part in the shape of a triangular prism. The dimensions of this part are shown below. Which estimate is closest to the volume in cubic millimeters of the part?


108 
217
440 
880

Answer 1

The closest estimate is 108.

The volume of a triangular prism is found using the formula

V = 1/2*b*h*H, where b is the base of the triangle, h is the height of the triangle, and H is the height of the prism.  With our information we have:

V=1/2(12.6)(1.6)(10.75) = 108.36.
