Find the length of the base of a square pyramid if the volume is 48 cubic inches and has a height of 9 inches. 4 inches 8 inches 16 inches 24 inches

4 inches

Step-by-step explanation:

In order to calculate the length of the base of a square pyramid you just have to work the formula backwards, you have the value for the height and the volume, the formula for the square pyramid is the next one:

And we just insert the values we know into the formula:

Now we clear the Ab from the formula:

We know that the area of the base is equal to 16, and as we know the formula for the area of a square is:

So if the area is 16 we just calculate the square root and the length of the side is 4.

88 : 2 ::  x : 60   proportion

(88)(60) = 2x     product of means extremes

5280 = 2x          multiply

264 = x              divide both sides by 2
