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 i think it is HELPFUL Step-by-step explanation: |
