Question

What is the total surface area of a cuboid with dimensions 12cm, 10 cm and
8cm.

Answer 1

Step-by-step explanation:

TSA of cuboid=2(lb+bh+hl)

=2(12*10+10*8+8*12)

=2(120+80+96)

=2(296)

=592

Answer 2

$\huge\bf\underline{\underline{Given:}}$

Length of Cuboid = 12 cm

Breadth of Cuboid = 10 cm

Height of Cuboid = 8 cm

$\huge\bf\underline{\underline{To\:Find:}}$

Total Surface Area of Cuboid

$\huge\bf\underline{\underline{Solution:}}$

Total Surface Area of Cuboid

$2<strong>(</strong>lb+bh+hl)\\2[(12)(10)+(10)(8)+(8)(12)]\\2(120+80+96)\\2(296)\\592cm^2$

Therefore, total surface area of cuboid is 592 sq.cm.
