An open rectangular box externally measures 4m x 3m x 4m. Find the total cost of painting the box externally if it costs N2.00 to paint one square meter
N96.00
N112.00
N136.00
N160.00
Correct answer is B
Total surface area(s) = 2(4 x 3) + 2(4 x 4)
= 2(12) + 2(16)
= 24 + 32
= 56cm2
1m2 costs N2.00
∴ 56m∴ will cost 56 x N2.00
= N112.00
