The length, breadth and height of a cuboid are 10 cm, 6 cm and 4 cm respectively. What is the total surface area?
Dimensions of cuboid $$l=10$$ cm , $$b=6$$ cm and $$h=4$$ cm
Total surface area of cuboid = $$2(lb+bh+hl)$$
= $$2[(10 \times 6)+(6 \times 4)+(4 \times 10)]$$
= $$2(60+24+40)$$
= $$2 \times 124 = 248$$ $$cm^2$$
