Answer:
Since we have given that
There is a prism having equilateral triangle as a base.
Height of prism = 29 yd
Length of base = 10 yd
As we know the formula for "Volume of prism"-Area of base × height
Here, Area of base = Area of
equilateral triangle = 3 × a²
Volume = Area of base × height
Volume √3 4 × 10 x 10 x 29
Volume = 1255.7 yd³
