Find the volume of a square pyramid with a base length of 9cm and a height of 4cm
then you have not read your material. The base is a square of side 9cm, so its area is 9^2 = 81cm^2
Your formula for volume then tells you it is
1/3 * 81 * 4 = 108 cm^3
v = 1/3 Bh
with B=9^2 and h=4
Still don't get it
Thx Steve. But no need to be passive aggressive lol.
To find the volume of a square pyramid, you can use the formula: V = (1/3) * base_area * height. In this case, the base of the pyramid is a square, so the base area can be found by squaring the length of one side.
1. Calculate the base area of the pyramid:
The length of one side of the base is given as 9cm.
Therefore, the base area = (side length)^2 = 9cm * 9cm = 81cm^2.
2. Plug in the values into the volume formula:
V = (1/3) * base_area * height
V = (1/3) * 81cm^2 * 4cm
3. Multiply and divide:
V = (1/3) * 324cm^3
V = 108cm^3
The volume of the square pyramid is 108 cubic centimeters (cm^3).
