Find the volume and surface area of the cubes whose. Sides are—5cm, 4.5cm, 8cm 
Answers
Step-by-step explanation:
Given:
The cube whose side are i]5cm ii)4.5cm iii)8cm iv)3.5cm v)6cm
To find:
The volume and surface area
Solution:
We know,
\begin{gathered}\boxed{\bold{Volume \:of\:a \:cube = Side^3}}\\\\\boxed{\bold{Curved\:Surface\:Area \:of\:a \:cube = 4\times Side^2}}\\\\\boxed{\bold{Total\:Surface\:Area \:of\:a \:cube = 6\times Side^2}}\end{gathered}

Cube with side = 5 cm:
Volume = 5³ = 125 cm³
C.S.A = 4 × 5² = 100 cm²
T.S.A = 6 × 5² = 150 cm²
Cube with side = 4.5 cm:
Volume = 4.5³ = 91.125 cm³
C.S.A = 4 × 4.5² = 81 cm²
T.S.A = 6 × 4.5² = 121.5 cm²
Cube with side = 8 cm:
Volume = 8³ = 512 cm³
C.S.A = 4 × 8² = 256 cm²
T.S.A = 6 × 8² = 384 cm²
Cube with side = 3.5 cm:
Volume = 3.5³ = 42.875 cm³
C.S.A = 4 × 3.5² = 49 cm²
T.S.A = 6 × 3.5² = 73.5 cm²
Cube with side = 6 cm:
Volume = 6³ = 216 cm³
C.S.A = 4 × 6² = 144 cm²
T.S.A = 6 × 6² = 216 cm²
