Question

diagonal of a cube shaped tank measures 5.19 given root 3 is equal to 1.73 how many kilo litres of water can be filled in the tank​

Answer 1

Answer:

We know that

Volume of cube =a

3

By substituting the values

Volume of cube a

3

So we get

Volume of cube =729 m

3

We know that

Lateral surface area of cube =4a

2

By substituting the values

Lateral surface area of the cube =4×9

2

So we get

Lateral surface area of cube =4×81=214 m

2

We know that

Total surface area of cube =6a

2

By substituting the values

Total surface area of cube =6×9

2

So we get

Total surface area of cube =6×81=486 m

2

We know that

Diagonal of cube =√3a

By substituting the values

Diagonal of cube =1.73×9=15.57 m

Therefore, thew volume is 729 m

3

, lettral surface area is 324 m

2

, total surface area is 486 m

2

and the diagonal of cube is 15.57 m.
