Question

In a right rectangular pyramid with base edges a=18 cm and b=10 cm the slant height towards a is k=13 cm while the slant height towards b is l=15 cm. Find The volume of the pyramid, if h=12 cm

Answer 1

As, 
a=18 cm
b=10 cm
h=12 cm
volume of pyramid= (a*b*h)/3
                              =(18*10*12)/3
                              =720 cm³
