A child’s sandbox is 1.5 m wide, 1.5 m long and 75 cm deep. If there are on average 55 grains of sand per mm3 , how many grains of sand are there in the sandbox?

Convert the sides to mm,
1.5 x1000=1500mm
75cm x10=750
1500 x1500 x 750=1,687,500,000 mm^3 (This is the volume of the box in cubic mm)
Then 1,687,500,000 x55=92,812,500,000 grains of sand in the box. Phew!!!!
