Question

Two solid cubes of side 10 cm each are joined end to end. What is the volume of the resulting cubiod
please with explation ​

Answer 1

Answer:

1000cm3

Step-by-step explanation:

Length of new cuboid, l=10+10=20 cm,

height h=10 cm

and width b=10 cm

Surface Area of Cuboid =2(lb+lh+bh)

=2(20×10+20×10+10×10)

=2(200+200+100)

=1000 cm

Answer 2

Answer:

2000cm³

Step-by-step explanation:

Volume of a cube is given by a³ (a×a×a) where a is the length of the side.

Here there are 2 cubes with side of length a = 10cm

Volume of each cube would be 10³ = 10×10×10 = 1000cm³

If the 2 cubes are joined, the resultant volume would be the sum of the volume of 2 cubes. As the 2 cubes have same side length the volume would be

2×1000 = 2000cm³
