Answer:
Required total cost is Rs.237600
Step-by-step explanation:
If five cubes of 6 m each are placed side by side and stuck together to make it a cuboid , then the length of the cuboid = 5×6 = 30 m
width of the cuboid is 6 m and height also 6 m
total surface of the cuboid is {4×(30×6)+2×(6×6)} m^2
= 4×180+2×36 = 720+72 = 792 m^2
total cost = 792×300 =237600 rupees
