Question

3. The volume of a cuboid whose length, breadth and height are in the ratio of 3:1:2 is :
(a) 8 x breadth^3 (b) 8 x length^3 (c) 6 x breadth ^3(d) length x breadth
​

Answer 1

Answer:

Let the length breadth and height of the cuboid be x,2x and 3x units.

The dimensions after increase are x+

100

100

x, 2x+

100

200

×2x, 3x+

100

200

×3x.

i.e., 2x,6x and 9x

Original volume =x×2x×3x=6x

3

Increased volume =2x×6x×9x=108x

3

∴ Increase in volume =108x

3

−6x

3

=102x

3

=17×6x

3

=17× original volume
