The volume of a pyramid is computed by multiplying the base length, base width, and pyramid height and divide it by 3.
Volume = (base length x base width x height)/3
since this is a square, base length and width are equal.
w=l=10cm
h=12cm
Substituting the given values in the formula, we will get the volume of the pyramid
Volume=(10cmx10cmx12cm)/3
Volume= 400cm^3
I think it’s 300 the answer
42x39=1,638
Remember that the formula for finding the area of a square is base x high
So the answer is 1,638 square meters
