find the volume of a square pyramid with a base length of 9cm and a height of 4cm. ANSWER: 108 cm^3 (is it right?)
1/3 * 9^2 * 4 = 108
good job
yay thank you @steve (:
To find the volume of a square pyramid, you can use the formula:
Volume = (1/3) x Base Area x Height
The base area of a square pyramid is calculated by multiplying the length of one side of the square base by itself. In this case, the base length is 9 cm, so the base area is 9 cm x 9 cm = 81 cm².
Plugging in the values, we have:
Volume = (1/3) x 81 cm² x 4 cm
Volume = (1/3) x 324 cm³
Volume = 108 cm³
So, your answer of 108 cm³ is correct.
To calculate the volume of a square pyramid, you can use the formula:
Volume = (1/3) * Base Area * Height
In this case, the base of the pyramid is a square with a side length of 9 cm, so the base area can be calculated using the formula:
Base Area = Side Length * Side Length
Base Area = 9 cm * 9 cm = 81 cm^2
Now, substitute the values into the volume formula:
Volume = (1/3) * 81 cm^2 * 4 cm
Volume = (1/3) * 324 cm^3
Volume = 108 cm^3
So, the correct answer is indeed 108 cm^3.
