Question

if 4 cubesof edge 3cm each are joined end to end . find the volume of the cuboid so formed

Answer 1

each cube dimensions 3x3x3
when we join them the figure form is de cuboid with dimensions 3x3x12
so volume of volume =3x3x12
=1ò8cm 3

Answer 2

let the edge of the cube = a = 3cm
if 4 such cubes are joined end to end one cuboid formed
then dimensions of the cuboid are
length = l= 4a = 4*3 = 12cm
width = w= a =3 cm
height = h =a = 3cm
volume of the cuboid = lbh
 = 12cm *3cm *3cm
=108 cubic cm
