Answer 1

Thats not a cube its cuboid having dimension 7*8*5cm.Cube has same sides

Answer 2

Hlo friend.. Cutiepie Here.

Here is ur answer :

1. Side of the cube = 7 cm

Total surface area = 6 × ( side )²

= 6 × ( 7 )²

= 6 × 49

= 294 cm²


Curved surface area = 4 × ( side )²

= 4 × (7)²

= 4 × 49

= 196 cm²

2. Side of the cube = 8 dm

Total surface area = 6 × ( side )²

= 6 × ( 8) ²

= 6 × 64

= 384 dm²

Curved surface area = 4 × ( side )²

= 4 × ( 8) ²

= 4 × 64

= 256 dm²

3. Side of the cube = 5 cm

Total surface area = 6 × ( side )²

= 6 × ( 5) ²

= 6 × 25

= 150 cm²

Curved surface area = 4 × ( side )²

= 4 × ( 5 )²

= 4 × 25

= 100 cm².
