Answer:
Step-by-step explanation:
Surface 1 = 25
Surface 2 = 25
Surface 3 = 25 * 2
TSA = 2 (Sur1+Sur2+Sur3)
= 2 (25+25+50)
= 2 (100)
= 200 cm^2

Given,
Edge of the cube =5 cm
Solution
After joining two cubes,
Total length, l=5+5=10cm
Breadth, b=5cm and
Height, h=5cm
∴ Surface Area =2(lb+bh+lh)
=2(10×5+5×5+5×10)
=2×125
=250cm
Hence, the surface area of the resulting cuboid is 250 cm
