Question

5
6) A cubical hall can hold 74.088 m' of air. What is
the height of the hall?​

Answer 1

Answer:

The answer is 4.2 m

Step-by-step explanation:

h×h×hh^3=74.088h=(74.088)^1/3=4.2m

Answer 2

Answer :

• 4.2 m is the height of wall

Given :

• A cubical hall hold 74.088 m of air

To find :

• Height of hall

Solution :

To find the height of hall we need to use the formula of volume of cube

Given , A cubical hall can hold 74.088 m of air

We know that,

• Volume of cube = (a)³

➟ a³ = 74.088m

➟ a = (74.088)⅓

➟ a = 21/5

➟ a = 4.2m

Hence , 4.2 m is the height of wall

More Explanation :

• A cube has 6 faces
• A cube has 8 vertices
• A cube has 12 edges
• Lateral surface area of cube = 4a²
• Total Surface area of cube = 6a²
• Volume of cube = a³
• Length of Diagonal of cube = √3 a
• A cube is a 3D shape
• Diagonal of face of the cube = √2 a
• Edge of cube = (Volume)⅓
