Question

the outer surface of a cube of side 6m is to be painted.if the coast of painting is rs 2 per 100 sq.cm,find the total coast of painting the cube​

Answer 1

Step-by-step explanation:

Given the side of the cube =6m

Total surface area of the cube =6×(side)²

=6(6)²

=6×36 = 216m²

The cost of painting is Rs.2 per 100cm²

∴ cost of 1cm² =

$2 \div 100$=Rs.0.02

we know that 1m² =10000cm²

216 m² =2160000cm²

Hence total cost of painting the cube

=2160000×0.02=Rs.43200 (Ans)
