Question

Find the total surface area of a cuboid with length 10cm ,breath 8cm and heigth 5cm.​

Answer 1

Answer:

Total surface area of a cuboid=2(lb+bh+hl)

Given, l=10cm b=8cm h=5cm

2[(10)(8)+(8)(5)+(5)(10)]

2[80+40+50]

2[170]

340cm²

Answer 2

Step-by-step explanation:

Given,

Length of Cuboid = 10cm

Breadth of Cuboid = 8cm

Height of Cuboid = 5cm

To Find :-

Total Surface area of Cuboid(T.S.A)

Formula Required:-

Let,

Length of Cuboid be 'l'

Breadth of Cuboid be 'b'

Height of Cuboid be 'h'

Total surface Area of Cuboid be 'A'

A = 2(lb + bh + hl)

Solution:-

Total surface Area of Cuboid =

$\sf 2(10cm(8cm)+8cm(5cm)+5cm(10cm))$

$\sf 2(80cm^{2}+40cm^{2}+50cm^{2})$

$\sf 2(170cm^{2})$

$\sf 340cm^{2}$

$\sf\therefore T.S.A = 340cm^{2}$
