The dimensions of a cuboid are 120 cm × 60 cm × 30 cm. What is the total surface area of a cube whose volume is same as that of cuboid?

Answer»

The Answer is  14,400 cm2.

Given:-

dimensions of cuboid=120*60*30. 

Volume of Cuboid=l*b*h

Volume of Cuboid=120*60*30= 2,16,000  cm3

Volume of Cuboid = Volume of Cube = 2,16,000   [given]

Volume of Cube= aor side3

2,16,000= a3

60=a

TSA of Cube= 4a2

TSA=    4*(60)2  = 14,400 cm2
