Calculate the total surface area of a cupboard which measures 12cm by 10cm by 8cm
A
1920cm\(^2\)
B
592cm\(^2\)
C
296cm\(^2\)
D
148cm\(^2\)
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Total surface area of a cupboard is given by the equation A = 2(lb + bh + lh) L = 12, b = 10, h = 8
A = 2((12 x 10) + (10 x 8) + (12 x 8))
A = 2(120 + 80 + 96)
A = 2 x 296
A = 592cm\(^2\)
Answer is B
