The length, breadth, and height of a brick are 10 cm, 4 cm, and 3 cm, respectively. Find the surface area of the brick?
Answer & explanation
Correct answer: option 4
If only surface area is mentioned in the question, we assume it to be Total surface area. TSA of brick is 2(lb + bh + hl).
Length- 10
Breadth- 4
Height- 3
Total surface area = 2(lb + bh + hl)
Total surface area = 2(10x4 + 4x3 + 3x10)
Total surface area = 2(40 + 12 + 30)
Total surface area = 2(82)
Total surface area = 164 cm2
