A square pyramid has a base side length of 40 cm and a height of 51 cm. What is its volume?
v=a^2 h/3
is this correct?
40^2 x 51/3
= 27200 cm3 ?????
thank you
looks good
Yes, you are correct! The formula for the volume of a square pyramid is V = (base area x height) / 3, where the base area is equal to the square of one side length. In this case, the base side length is 40 cm, so the base area is (40 cm)^2 = 1600 cm^2. The height is 51 cm. Plugging these values into the formula:
V = (1600 cm^2 x 51 cm) / 3
= 81600 cm^3 / 3
= 27200 cm^3
Therefore, the volume of the square pyramid is 27200 cm^3. Well done!
