Question

the diagram shows the dimensions of an office. It costs about $0.11 per year to air condition one cubic foot of space. On average, how much does it cost to air condition the office for 1 month??

Answer 1

Volume = Length x Width x Height = 12 x 32 x 25 = 9600 ft²

1 ft² = $0.11
9600 ft² = 9600 x 0.11 = $1056

1 Year = $1056
12 Month = $1056
1 Month = $106 ÷ 12 = $88

Answer: It costs $88 to aircon the office every month.
