A box whose length, breadth, and height are 5 cm, 2 cm, and 3 cm respectively. Its total surface area is?
Answer: 62 cm²
Explanation
To find the total surface area (TSA) of the box:
TSA = 2(lb + bh + hl)
Given length (l) = 5 cm, breadth (b) = 2 cm, and height (h) = 3 cm:
TSA = 2(5_2 + 2_3 + 3*5)
= 2(10 + 6 + 15)
= 2(31)
= 62 cm²
