Question

Find the total surface area , lateral surface area and the length of the diagonal of the cube whose edge is 3.2m. ​

Answer 1

Step-by-step explanation:

We know that

Volume of cube =a3

By substituting the values

Volume of cube a3

So we get

Volume of cube =729 m3

We know that

Lateral surface area of cube =4a2

By substituting the values

Lateral surface area of the cube =4×92

So we get

Lateral surface area of cube =4×81=214 m2

We know that

Total surface area of cube =6a2

By substituting the values

Total surface area of cube =6×3

So we get

Total surface area of cube =6×9=54m2

We know that

Diagonal of cube =√3a

By substituting the values

Diagonal of cube =1.73×3=5.19 m
