Square-shaped 9491

A square-shaped pool with bottom dimensions of 7m * 4m and a height of 1.2m needs to be painted. How much will the paint cost if 1 kg of paint, which is enough for 6 m2 of color, costs 3 euros? The painter charges 1 euro for coating 1 m2.

Correct answer:

x =  81.6 Eur

Step-by-step explanation:

a=7 m b=4 m c=1.2 m  S=a b+c (2 a+2 b)=7 4+1.2 (2 7+2 4)=5272=54.4 m2  x=S/6 3+S 1=54.4/6 3+54.4 1=81.6 Eur
