Question

The volume of a cuboid is 504√5cm2. If the ratio between its height is√2:√5 then find the breadth of the cuboid. (Where length of the cuboid is 7√2 cm.) *

a. 6√2cm

b. 3√2cm

c. 2√2cm

d. 8√2cm​

Answer 1

ANSWER

Consider a given The given The length, breadth and height of a cuboid are in the ratio 5:4:2 and the total surface area is 1216cm2,

Let, the dimension of cuboid are l=5x,b=4x and h=2x

Now, the surface area of cuboid =2(5x×4x+4x×2x+2x×5x)=76x2

Now,

76x2=1216

x2=16

x=4

Dimensions of cuboid are,

l=5x=5×4=20cm,b=4x=4×4=16cm

h=2x=2×4=8cm

Volume of cuboid=l×b×h=20×16×8=2560cm3

 

Hence, this is the answer.
