Question

Two boxes cube with edges a=38 cm and b = 81 cm is to be replaced by one cube-shaped box (same overall volume). How long will be its edge?​

Answer 1

Answer:

83.697 cm

Step-by-step explanation:

Let the edge be x.

Then

x = 3√{ (38)^3 + (81)^3 = 83.697

Hence,

edge = x = 83.697 cm

Answer 2

Answer:

Let the edge be x.

Then,

x = 3V{ (38)^3 + (81)^3 = 83.697

Hence,

edge = x= 83.697 cm
