Answer
Step-by-step explanation:
Area of sheet = Surface area of the tank
Surface area of the tank = Area of 4 walls of the tank + Area of its base
A=20×8+8×12+20×8+8×12+20×2
A=160+96+160+96+240
A=752m
2
Area of sheet = Surface area of the tank
L×2.5=752
L=300.8 m
Length of the sheet =300.8 m
∴ cost of the sheet =C=300.8×12.50
