Question:

The volume of a wall, six times as high as its breadth and half as long as its height, is 23958 cm3. What is the breadth of the wall?

Options:

21 cm

15 cm

11 cm

18 cm

Correct Answer:

11 cm

Explanation:

The volume of a wall = 23958 cm3

Volume of a cuboid = Length × Breadth × Height

Let the height = 6a,

breadth = a

length = 3a

According to the concept,

3a × a × 6a = 23958

= a3 = \(\frac{23958}{18}\)

= a= 1331

= a = 11
