Question

solid cube of side 3 centimetre are are joined to form a cuboid find the surface area​

Answer 1

Edge of cube (A)= 3cm

Length of resulting cube=5×3=15

Hieght of resulting cuboid =3cm

And,

Breadth of resulting cuboid=3cm

TSA resulting cuboid=2(IB+BH+HL)

=> 2 (15×3+3+3+3×15)

=> 2 (45+9+45)

=> 2 × 99

=> 198 cm square

Hence,

TSA of resulting cuboid =198 cm square
