Answer :
- Side of cube is 6m
Given :
- 8 persons can stay in a cubical room
- Each person requires 27m³of air
To find :
- The side of cube
Solution :
Given that Air required by each person is 27m³ so ,
- Air required by each person is 27m³
- Air required by 8 peoples means person can stay in room = 27 × 8 = 216m³
As we know that volume of cube : a³
- Volume of cubical room is 216m³
➼ 216m³
➼ ³√216m
➼ ³√(2×2×2) (3×3×3)
➼ ³√2³ × 3³
➼ 2 x 3
➼ 6cm
Hence, The side of cube is 6m.
More Explanation:
- Volume of cube = a³
- surface area of cube = 6a²
- Diagonal of cube = √3
- Edges of cube (a) = ³√v
- Where a is edges , v is volume d is Diagonal
