Question

If the length of a diagonal of a cube is 64m.Find its surface area and volume

Answer 1

Lateral surface area of a cube = 4×side²

64 = 4 × side²

64÷4 = side²

16. = side²

$\sqrt{16 } = 4m$

Total surface area of cube = 6 × side²

= 6 × 16²

= 96 m²

Volume of a cube = side³

= 4³

= 64 m³

Answer 2

Answer:

$Hey dear ,$

$\huge\mathbb\blue{Given ,}$

length of diagonal of a cube= 64m

Volume of a cube = 64m^3

$(side)^3 =64$

Side ^3 =4 ^3

Side =4 m

Total surface Area =6(Side)^2

6*4^2

6×16

96m^2 .

Total surface area = 96m^2

= 262,144 .
