The total surface area of a cuboid is 236 cm². Its length is 8 cm and height is 6 cm. Find its breadth (in cm).

Correct option is D

· Total Surface Area = 236 cm²
· Length, l = 8 cm
· Height, h = 6 cm
Substitute the known values into the formula:
236=2(8b+b⋅6+6⋅8)
Simplify inside the parentheses:
236=2(8b+6b+48)
Combine like terms:
236=2(14b+48)
Divide both sides by 2:
118=14b+48
Subtract 48 from both sides:
70=14b
Divide both sides by 14:
b=5
