Question

find the weight of cube of M.S. of 14 cm side with its density being 7.8 gm/cc.

Answer 1

Side length is 14 cm
Thus volume is 2744 cc

Thus mass = volume×density
M = 2744×7.8
M = 21403.2 gm = 2.14032 kg

Answer 2

Answer:

2.14 gm

Step-by-step explanation:

Given : Side = 14 cm

To find: find the weight of cube of M.S. of 14 cm side with its density being 7.8 gm/cc.

Solution:

Side length is 14 cm

Volume of cube = $side^3$

                           = $14^3$  

                           = $2744$  

$Mass =Volume \times Density$

$Mass =2744 \times 7.8$

$Mass =2.14032$

Thus the Mass of cube is 2.14 gm
