Question

find the total surface area of cuboid ​

Answer 1

$\huge\mathfrak{Answer :}$

Given,

Length = 2.5 cm

Breadth = 2 m = 200 cm

Height = 240 cm

Total Surface Area = 2 [ lb + bh + hl ]

= 2 [ 2.5 × 200 + 2 × 240 + 240 × 2.5 ]

= 2 [ 500 + 480 + 600 ]

= 2 × 1580

= 3160cm^2 or 31.6 m^2

Since, 1 m = 100 cm

So, 3160cm^2 in Meters = 3160/100 = 31.6 m^2
