Question

three solid metal cubes with edges 6cm, 8cm and 10cm respectively are melted together and formed into single cube find the volume of new cube ​

Answer 1

Answer:

hope it helps.

Step-by-step explanation:

cube 1

s1= 6cm

volume=s1³ = 6³ = 216 cm³

cube 2

s2= 8cm

volume= s2³ = 8³ = 512 cm³

cube 3

s3 = 10cm

volume = s3³ = 10³ = 1000 cm³

volume of new cube = s³ = s1³+ s2³+ s3³

= 216 + 512 + 1000

=1728 cm³

edge of new cube = (1728)⅓

= 12 cm.
