Question

find the surface area of a box whose length is 40cm and breadth 27cm and height 10cm

Answer 1

The surface area of a box is $3520cm^2.$

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 $= 2(lb+bh+hl)$

$= 2(40\times 27 + 27 \times 10 + 10 \times 40 )$

$= 2(1080+270+400) cm^{2}$

$= 2\times 1750 cm^{2}$

$= 3520cm^2$

Hence, the surface area of a box is $3520cm^2.$

Answer 2

The surface area of a box whose lengths are given is 3520 $cm^2$

Step-by-step explanation:

Given:

Find the surface area of a box whose length is 40cm and breadth 27cm and height 10cm

Solution:

Surface area of a cuboid box = 2(lb + bh + lh)

= $2(40 \times 27 + 27 \times 10 + 10 \times 40)$

= 2(1750)

= 3520 $cm^2$

Result:

The surface area of the box is 3520 $cm^2$.
