volume of right triangular prism: L=7 W=2 H=3
To calculate the volume of a right triangular prism, you use the formula:
Volume = (1/2) * base * height * length
In this case, the base of the prism is a right triangle with dimensions of 7 (base) and 2 (height), and the length of the prism is 3.
To find the area of the base of the prism:
Area = (1/2) * base * height
Area = (1/2) * 7 * 2
Area = (1/2) * 14
Area = 7
Now we can calculate the volume of the prism:
Volume = 7 * 3
Volume = 21
Therefore, the volume of the right triangular prism is 21 cubic units.
