How many shots each having diameter 3 cm can be made from a cuboidal lead solid ofdimensions 9cm x 11cm x 12cm?​

Answer»

Answer:

he dimensions of a cuboid lead solids = 9 CM * 11 cm * 12 cm

The diameter of spherical lead shot, d = 3cm

The RADIUS of spherical lead shot, R = 1.5 cm

Volume of cuboidal lead solids = l * b * h = 9 cm * 11 cm * 12 cm = 1188 cm^3

Let total number of spherical lead shots = n

Volume of spherical lead shots = 4 * pi * r^3 = 4 * 22/7 * (1.5)^3 = 99/7 cm^3

Volume of cuboidal lead solids = n * volume of spherical lead shots

1188 = n * 99/7

n = 1188 * 7 /99

84
