Answer: 
Step-by-step explanation:
Given : Starks sculpture 30 cubed is a cube with sides 30 inches long.
We know that the volume of a cube is given by :-

Then , the volume of Starks sculpture 30 cubed will be :



Hence, the required volume = 
Short leg = ?
Long leg = 1/2x + 11
Hypotenuse = 2x + 1
For this you'd need to use the Pythagorean Theorem to find the short leg.
Pythagorean Theorem - a^2 + b^2 = c^2
B
