Find the volume of a square pyramid with a base length of 9 cm and a height of 4 cm.
324 cm3
108 cm3
36 cm3
152 cm3
i think it could be d or b im kinda leaning towards d though
miss sue?
Volume pyramid = (base * height)/3 = (9^2 * 4)/3 = ?
(but I'm not MsSue)
To find the volume of a square pyramid, you can use the formula: V = (1/3) * B * h, where V is the volume, B is the area of the base, and h is the height.
In this case, the base of the square pyramid is a square with a side length of 9 cm. So, the area of the base (B) can be calculated as length * width = 9 cm * 9 cm = 81 cm^2.
Now, substitute the values into the volume formula:
V = (1/3) * 81 cm^2 * 4 cm
V = (1/3) * 324 cm^3
V = 108 cm^3
So, the correct answer is 108 cm^3, option (b).
