Given:
Area of base = 90 ft²
Length of the prism = 13 ft
To find:
Volume of the triangular prism
Solution:
Volume of triangular prism formula:
Volume = Area of base × length of prism
Substitute the given values in the formula.
= 90 × 13
Volume = 1170
Therefore, the volume of the triangular prism is 1170 ft³.
