A contractor rents a trailer truck to haul materials. The inside of the
trailer is 20 feet long, 7 feet wide,
and 8 feet high. Find the storage
capacity of the trailer in cubic feet.

1120ft^3

Step-by-step explanation:

The side x is the hypotenuse of the triangle.

And we know that the leg that is labeled with a line is also 6.

Use the Pythagorean theorem and solve for x.

a² + b² = x²
3² + 6² = x²
9 + 36 = x²
45 = x²
√45 = x
√9×5 = x
√9√5 = x
3√5 = x

The answer is 3√5

Hope this helps :)
