Total surface area of cuboid =2*(length *breadth+breadth *height + height *length)=50 square m....... (1)
Lateral surface area of cuboid =2(breadth *height + height *length) =30 square m.......... (2)
subtracting (2) from (1)
2(length *breadth) =14 square m
L * B=14÷2 square m
=7 square metre
Area of the base of cuboid =7 square metre
