The children on the beach have been busy buliding sand pyramids all day. One of their pyramids \( 1525,4 \mathrm{~cm} t \) all and has a square base with edges measuring \( 38 \mathrm{~cm} \) in length. How much sand did they use to construct their pyramld? Report your answer in \( \mathrm{cm}^{3} \) but do not include the unit \( \mathrm{cm}^{3} \) in your answer box. Round your answer to the nearest whole \( \mathrm{cm}^{3} \). Do not include commas in your answer submission. The formula for the volume of a pyramid is \( V=\frac{1}{3} l^{2} h \).
