Answer: 80 cubic centimeters
Step-by-step explanation:
Use the formula: V=
Bh
(B is the area of the pyramid's base)
V=
(16)(15)
Multiply: 16 x 15 =240
x 240 = 80
V= 80cubic centimeters
The Area of a rectangle is Length times Width.
3 * (x+4) = 36
3x + 12 = 36
3x = 24
x = 8. So the length of the rectangle is 12
