Question

Sally really wanted a home that was 40 metres long on all four sides, and 80 metres high. If Milton could find some bricks that were measured at 0.5 metres by 0.5 metres, how many would he need to complete the building?

Answer 1

for one side, you need 80 x 160 = 12,800 bricks. For four sides, you need 51,200 bricks. Roughly, because brickwork never works perfectly.
