Question

Two cubes each of edge 5 cm are joined end to end.The surface area of the resulting cuboid is?

Answer 1

Answer:250 cm^2

Step-by-step explanation:Side of each cube = 5 cm

When they are joined they become cuboid.

Length of cuboid = 10 cm

Breadth of cuboid = 5 cm

Height of cuboid = 5 cm

Lateral/ Curved Surface Area of cuboid

= 2(l+b) h

= 2×(10+5)×5

= 2× 15×5

= 150 cm^2

Total Surface Area of cuboid

= 2(lb+lh+bh)

= 2(10×5+10×5+5×5)

= 2(50+50+25)

=2×125

= 250 cm^2.
