becomes ......times the original area.
1.4
2.8
3.12
4.16​

Answer 1

Step-by-step explanation:

Let the length, breadth and height of the initial cuboid be l,b, and h respectively.

Therefore, new length = 4l

New breadth = 2b

New height =

3

1

h

Initial Volume = lbh

New Volume =

3

1

×2×4(lbh) =

3

8

lbh
