Answer:
1,664 square yards
Step-by-step explanation:
Given: A triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards. The other two sides of the triangle are each 20 yards.
Surface area of the triangular prism:
The formula to determine the surface area of the triangular prism is
SA= bh+PL
where base: b=24
height: h=16
length: l=20
Perimeter: P= 20+20+24= 64
Next we follow the steps of the formula and our equation is:
SA= (24x16) + (64x20)
24x16= 384 and 64x20= 1280
384+1280= 1,664
SA= 1,664
the surface area of the triangular prism is 1664 square yards.
