Question

The length, breadth and height of a cuboid are in the ratio 5:3:2. If it's volume is 3750cm^3, Find its total surface area.

Answer 1

Answer:

1550 cm^2

Step-by-step explanation:

Let length be 5x

breadth be 3x

And height be 2x

ATP,

length *breadth *height =volume of cuboid

5x*3x*2x=3750

30x^3=3750

x^3=3750/30

x^3=125

(x)^3=(5)^3

x=5

Length=5x=5*5cm=25cm

Breadth=3x=3*5cm=15cm

Height=2x=2*5cm=10cm

Total surface area of cuboid = 2(length*breadth+length*height+breadth*height)

= 2(25*15+25*10+15*10) cm^2

= 2(375+250+150) cm^2

= 2*775 cm^2

= 1550 cm^2
