Alex made a sketch for a homemade soccer goal he plans to build. The goal will be in the shape of a triangular prism. The legs of the right triangles at the sides of his goal measure 4 ft and 8 ft, and the opening along the front is 24 ft. How much space is contained within the goal?

4 answers

area of triangle times the length.
The answer is 384ft because you first have to multiply 4ft and 8ft then divide it by 2 which is 16ft. Then you multiply 16ft with 24ft which is 384. So in the end the answer would be 384ft.
what is a subject matter achievevment gool
Explanation: V= B*h
B= 1/2( 4*8)= 1/2(32)= 16 inches ^ 2
Height of the prism= 24 inches
V= B*h= v= 24*16= V= 384 feet ^ 3
Answer= 384 feet ^ 3
