Question

2️⃣If every side of a room measures 4 m, how many cubic metres of air does it hold?

Answer 1

★ Given :

• Every side of the room measures 4m.

★ To Find :

We have to find that how many cubic meters of air does it hold ?

★ Explanation :

As, it is given that the measures of all the sides of the room is 4m. Then it is a cube because all the sides of a cube measures same.

Now, we have to find that how many cubic meters of air does it hold. So, we will calculate the volume of the room.

$\large{\star{\underline{\boxed{\sf{Volume = Side^3}}}}} \\ \\ \sf{\dashrightarrow Volume = 4^3} \\ \\ \sf{\dashrightarrow Volume = 64} \\ \\ \large{\star{\underline{\boxed{\sf{Volume = 64 \: m^3}}}}}$

So, 64 m³ of air room holds.

$\rule{400}{4}$
