The dimensions of an open metal box are 52 cm, 42 cm and 31 cm. Its thickness is 1 cm. If \( \Large 1\ cm^{3} \) of metal used in the box weighs one gram, then the weight of the box is

A) 7.04 kg.
B) 7.704 kg.
C) 7.64 kg.
D) 7.86 kg.

Correct Answer:


B) 7.704 kg.

Description for Correct answer:
Volume of metal = \( \Large \left(52 \times 42 \times 31-50 \times 40 \times 30\right)\ cm^{2} \)

=\( \Large \left(67704 - 60000\right)\ cm^{2} \)

=\( \Large 7704\ cm^{3} \)

Weight of the box = 7704 gm

= 7.704 kg.
