Question

Find the side of the cube whose surface area is 253.5 m²

Answer 1

Answer:

Step-by-step explanation:

6a^2=253.5m^2

a^2=253.5/6=42.5

a=root 42.5=6.51m

Answer 2

$\texttt{let the Side of the cube be a.}$

$A/q$

$\texttt{ Total surface of the cube = 253.5 m²}$

$\implies \mathtt{6a² = 253.5}$

$\implies \mathtt{a² = \frac{ 253.5}{6}}$

$\implies \mathtt{a² = 42.25}$

$\implies \mathtt{a = \sqrt{42.25}}$

$\implies \texttt{a = 6.5}$

$\texttt{Therefore, side of the cube is 6.5 m}$
