Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V = , where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V =
V = 28 ft³
So we start by combining like terms;
Now we have;
We then subtract 1 from both sides;
Then we divide both sides by 5;
Leaving the final answer to be h = -2
