Question

FInd the volume of the square pyramid shown round to the nearest tenth if necessary 11cm 11cm 15cm

Answer 1

So to find the volume of a square pyramid, the formula is 1/3B2h or Base squared times height divided by 3 because of the triangular pyramid. So the base is 11, the height is 15 so 11 squared is 121 and the height is 15, so 121 times 15.

121 x 15= 1,815.

Now we divide by 3 because of the formula, so 1,815 divided by 3 is...


1,815 / 3= 605 cm squared!

Answer 2

Volume = 1/3 * area of base * height

=1/3 * 11^2 * 15

= 605 cm^3 Answer
