Answer:
528cm³
Step-by-step explanation:
The shape is a square pyramid, so we must use the equation of it, which is 1/3Bh.
In order to find B, base, you need to multiply the Length and Width of the Square, in this case, 12×12=144cm
The height of the shape is 11cm, as the picture states.
Then put the values into the equation and multiply to solve.
(1/3)(144)(11) = 528cm³
