Question

7) If two cubes of sides 1 cm each are joined end to end then the volume
of the cuboid is
2 cm
4 cm
8 cm
3 cm​

Answer 1

Answer:

2 cm

Step-by-step explanation:

If two cubes are joined their volume get's added up

So volume of cuboid is equal to twice the volume of a cube

Vol. of cube = a^3

Vol.of cuboid = 2*a^3

2*1^3

2*1= 2

Answer 2

Answer:

2 cubic cm

Step-by-step explanation:

length of cube=1 cm

width of cube=1 cm

height of cube =1 cm

If the 2nd cube is kept on top of the 1st cube

Then,

Height of the cuboid= 2cm

Lenght of cuboid = 1cm

Width of cuboid = 1 cm

Volume of cuboid = length×width×height

= 1×1×2

= 2cubic cm
