The number of cans of paint needed to paint the container is 2
The surface area of a cylinder can be found as follows;
surface area of a cylinder = 2πr(r + h)
where
Hence,
r = 4 / 2 = 2 ft
h = 4 ft
Therefore,
Surface area of the cylinder = 2 × π × 2(2 + 4)
Surface area of the cylinder = 2 × π × 2(6)
Surface area of the cylinder = 4π(6)
Surface area of the cylinder = 24π ft²
1 container = 24π ft²
10 containers = 240π ft²
Therefore,
400 ft² = 1 can of paint
240π ft² = ?
number of can of paint required = 753.6 / 400
number of can of paint required = 1.884
number of can of paint required = 2
Therefore, the number of cans of paint needed to paint the container is 2
