Question

Find the cost of painting a whole surface of cuboid with length 10 m, breadth 8 m, height 6 m

Answer 1

Step-by-step explanation:

Firstly we will calculate the whole surface of cuboid =2(lb+bh+hl)

$= 2((10 \times 8) + (8 \times 6) + (6 \times 10)) \\ = 2(80 + 48 + 60) \\ = 2(188) \\ = 376$

Now multiply it with the rate to find the total cost.
