Total area of wall = 24 m² and the number of cans of paint required is 4.8 cans
Given data
length = 3 m
width = 2 m
a can of paint will cover 10 m²
each wall needs 2 coats of paint
Area of a wall
= 3 * 2
= 6 m²
Assuming 4 walls, total area
4 * 6 = 24 m²
paints required:
since each wall needs 2 coats of paints then 1 can of paint will cover 5 m². for each wall which is 6 m² we have:
1 can = 5 m²
? = 6 m²
let x represent the number of cans for 6 m² then for x, we cross multiply
x = 6/5
x = 1.2 cans
for 4 walls we have
4 * 1.2 = 4.8 cans
