Question:
The dimensions of an open box are 50 cm, 40 cm, and 23 cm. Its thickness is 2 cm. If 1 cubic cm of metal used in the box weighs 0.5 gms, find the weight of the box.
A ) 7.04 kg
B ) 6.04 kg
C ) 8.04 kg
D ) 9.04 kg
Answer: C) 8.04 kg
Explanation :
The volume of the metal used in the box
= external volume – internal volume
= [(50 * 40 * 23) – (44 * 34 * 20)]cm3
= 16080 cm3
Weight of the metal =((16080*0.5)/1000)kg
= 8.04 kg.
