Question 1007994
.
A symmetrical square-based pyramid has height 10 cm and slant edges of 15 cm. Find the dimensions of its square base.
-------------------------------------------------------------------


Half of the base edge dimension is {{{sqrt(15^2-10^2)}}} = {{{sqrt(125)}}} = {{{5*sqrt(5)}}} cm.


Hence, the base edge dimension is {{{10*sqrt(5)}}} cm.
