Question

find the value lateral surface area and total surface area of a cube each of whose side measures 8 cm

Answer 1

Heya friend,

<><><><><><><><><><><><><><><><><>

Lateral surface area of a cube = 4 × (length)^2

=4 × 8 × 8

= 4 × 64

= 256 cm^2

Total surface area of a cube = 6 × (length)^2

= 6 × 8 × 8

= 6 × 64

=384 cm^2

Volume of a cube = Edge × Edge × Edge

= 8 × 8 × 8

= 512 cm^3

Thanks

Answer 2

✔️✔️Lateral surface area [LSA]of a cube :-

=4 ×a²

= 4 × 8 × 8

= 4 × 64 

= 256 cm²



✔️✔️Total surface area[TSA] of a cube :-

6 ×a²

= 6 × 8 × 8

= 6 × 64

= 384 cm²

a= length of the cube !
