Question

Q10. If the sides of two cubes are 2.5 cm
5.4 cm. Find their volumes?​

Answer 1

Answer:

Formula for finding the volume of a cube

= side*side*side

First cube = 2.5*2.5*2.5

=15.625 cm^3

Second cube = 5.4*5.4*5.4

= 157.464 cm^3

✰✰ ANSWER ✰✰

➙For 1st Cube : -

$\longmapsto\tt{Side\:of\:Cube=2.5cm}$

$\longmapsto\tt{\small{\boxed{\bold{\bold{\green{\sf{Volume\:of\:Cube={(Side)}^{2}}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{2.5\times{2.5}\times{2.5}}$

$\longmapsto\tt{{15.62cm}^{3}}$

☛Volume of 1st Cube is 15.62 cm³...

➙For 2nd Cube : -

$\longmapsto\tt{Side\:of\:Cube=5.4cm}$

$\longmapsto\tt{\small{\boxed{\bold{\bold{\blue{\sf{Volume\:of\:Cube={(Side)}^{2}}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{5.4\times{5.4}\times{5.4}}$

$\longmapsto\tt{{157.46cm}^{3}}$

☛Volume of 2nd Cube is 157.46 cm³..

l = length

b=breadth

h = height

a = side

• Surface Area of Cube = 6a²
• Surface Area of Cuboid = 2(lb+bh+hl)
• Volume of Cuboid = l × b × h
