HEYA MATE!!!
Given,
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. ( ans )
