Question

rectangular box has height ℎ cm . Its length is 7 times the height and breadth is 2 cm less than the length. What is the volume of the box?

Answer 1

Given:

A rectangular box with

• Height = h cm
• Length = 7h cm
• Breadth = 7h - 2 cm

What To Find:

We ave to find the volume of the rectangle box.

How To Find:

To find the volume of the box, we will use,

• Volume = Height × Length × Breadth

Solution:

Using the formula,

⇒ Volume = Height × Length × Breadth

Substitute the values,

⇒ Volume = (h) × (7h) × (7h - 2)

Remove the brackets,

⇒ Volume = h × 7h × 7h - 2

Take variable and numbers seperately,

⇒ Volume = (h × 7h × 7h) - 2

Multiply and solve,

⇒ Volume = 49h - 2 cm³

∴ Thus, the volume of the rectangular box 49h - 2 cm³.
