Answer 1

Answer:

Equal amount of wood is required.

Step-by-step explanation:

CUBE:

a = 6 cm

Volume of cube = $a^{3}$  = $6^{3}$  = 216 $cm^{3}$

CUBOID:

l = 9 cm

b = 8 cm

h = 3 cm

Volume of cuboid = l x b x h  = 9 x 8 x 3  = 216 $cm^{3}$

Thus, both cube and cuboid will require the same amount of wood to make.

Answer 2

Answer:

Equal amount of wood is required.

Step-by-step explanation:

CUBE:

a = 6 cm

Volume of cube = a^{3}a3  = 6^{3}63  = 216 cm^{3}cm3

CUBOID:

l = 9 cm

b = 8 cm

h = 3 cm

Volume of cuboid = l x b x h  = 9 x 8 x 3  = 216 cm^{3}cm3

Thus, both cube and cuboid will require the same amount of wood to make.
