Answer:
Result: The surface area of the box is 3520.
Step-by-step explanation:
Given,
Length(l) = 40cm, breadth(b) = 27cm and height(h) = 10cm
To find, the surface area of a box = ?
We know that,
The surface area of a box = 2(lb+bh+hl)=2(lb+bh+hl)
= 2(40\times 27 + 27 \times 10 + 10 \times 40 )=2(40×27+27×10+10×40)
= 2(1080+270+400) cm^{2}=2(1080+270+400)cm
2
= 2\times 1750 cm^{2}=2×1750cm
2
= 3520cm^2=3520cm
2
Hence, the surface area of a box is 3520cm^2.3520cm
