Question

18. Find the volume of a triangular prism with the following dimensions. Round to the nearest whole number.

Triangle base: 7ft
Triangle height 4ft
Prism height: 8.5ft

A. 20 ft^3
B. 65 ft^3
C. 119 ft^3
D. 238 ft^3

Answer 1

answer:119ft
7x8.5x4=238/2=119

Answer 2

The volume of a triangular prism with a triangle base of 7ft and height of 4ft, and a prism height of 8.5ft is approximately 119 cubic feet.

To find the volume of a triangular prism, you need to use the following formula: Volume = base area of the triangle * height of the prism. To find the base area of the triangle, you need to use the formula: Base area = (1/2) * base * height. Then, you can calculate the volume using the two formulas. Here is an example of how to calculate the volume of a triangular prism with a base of 7ft, a height of 4ft, and a prism height of 8.5ft:

Step 1: Calculate the base area.

Base area = (1/2) * 7ft * 4ft = 14ft^2

Step 2: Calculate the volume.

Volume = 14ft^2 * 8.5ft = 119ft^3 (rounded to the nearest whole number)
