The volume of the cuboid will be same as that of the lead shots.
Given:length of cuboid, l = 9 cmbreadth of cuboid, b = 11 cmheight of cuboid, h = 12 cm
Given:radius of lead shot, r =
No. of balls:
Therefore, 3600 Lead shots will be made from the cuboid.
The dimensions of a cuboidal lead solid =
= 9 cm × 11 cm × 12 cm
We need to find the number of spherical lead shots, each of diameter 3 cm that can be made from the cuboidal solid.
According to the given information, the length, the breadth and the height of the cuboidal lead solid are,
L = 9 cm, B = 11 cm, H = 9 cm
Let the required number of spherical lead shots be x.
The lead shot is spherical in shape.
Thus, volume of a lead shot = 4/3πr^3
As the diameter of each lead shot is 3 cm,
⇒Radius of a spherical lead shot =
= 1/2 x diameter
= 1/2 x 3
⇒Volume of the cuboidal lead solid = L x B x H
= 9 cm x 11 cm x 12cm
Volume of the spherical lead shot =
= (4/3) × (22/7) × (3/2)^3
Therefore the number of spherical lead shots x
= (9 x 11 x 12) / [(4/3) × (22/7) × (3/2)^3]
Thus, the required number of spherical lead shots is 84.
Explanation:Here us your answerhope this answer helps for youIf my answer is helpful to youPlease mark me as brilliant...
12 cm × 11 cm = 132...
132 cm × 9 cm =1188 cm
the answer is 1,188 cm✌
follow me..and mark b3 brainliest✌
Volume of the cuboid= 12×11×9
Volume of the lead shot= 4/3πr^3
No.of lead shots = volume of the cuboid/ volume of the lead shot
