Question 1
1 / -0

A cubical box of dimension 26 cm is constructed from a metal of thickness 2 cm. Find out the amount of metal used (in cm³).

A
7589

B
6928

C
6845

D
6752

Solution

Thickness of the cubical box = 2 cm
Internal dimension of the box = 26 cm – [2 + 2] cm = 22 cm

Internal volume of the box = 22 × 22 × 22 = 10,648 cm³
External volume of the box = 26 × 26 × 26 = 17,576 cm³

Volume of the metal used = External volume – Internal volume = 17,576 – 10,648 = 6928 cm³
