Lesson Steps
Step | Type | Explanation | Answer |
---|---|---|---|
1 |
Problem |
The volume of the triangular prism is 462 cubic feet and the length of the prism is 12 feet, the sides of the triangle height is 7 feet, find the base of prism ? |
|
2 |
Step |
The given volume and height and lengt of the prism is |
v = 462 |
3 |
Formula |
The volume of the triangular prism formula is |
v = \$1/2 times b times h times l\$ |
4 |
Step |
Substitute the values in the given formula, we get the base 'b' |
⇒ \$462 = 1/2 times b times 12 times 7\$ ⇒ \$462 = 0.5 times 12 times 7 times b\$ ⇒ 462 = 42b |
5 |
Step |
Move b coefficient into left hand side |
⇒ \$462/42\$ = b ⇒ 11 = b |
6 |
Formula |
The base of the triangular prism b is 11 meters. |
