Question

a cube of edge 2 cm is divided into cubes of edges 1 cm how many cubes will be made?find the total surface area of the smaller cubes ​

Answer 1

Step-by-step explanation:

volume of cubes with dge 2cm = a^3

= 2×2×2

8cm^3

volume of cubes with edge 1cm = a^3

= 1×1×1

1cm^3

number of cubes = volume of cubes with edge 2cm /volume of cubes with edge 1cm

= 8/1 = 8 cubes

TSA of the smaller cubes = 6a^2

= 6×(1)^2

= 6cm^2
