A monument is to be constructed in the form of a pyramid with base ABC in which AB = AC = 15M and BC = 20m. The vertex,v is 12m vertically above A

Calculate the area of triangle VAB
Calculate the area of triangle VBC

Special bricks for the outer faces are required and 14 bricks will cover 1m2

Estimate, to the nearest 1000, how many bricks are required
