Question

Find area of base ,area of vertical faces and total surface areaof a cuboid when length is 7cm breadth is 5cm and height 3cm​

Answer 1

Answer:

agar fir bhi problem h toh ek cuboidal box lekar uski length, breadth aur height par alag alag nishaan laga lo, fir dekho konse face ka area nikalte hue kon kon si do dimension ki zarurat h

Step-by-step explanation:

area of base=length×breadth=7×5=35 sq. cm

area of each vertical face= 7×3=21 sq.cm

total surface area=2×(length×breadth+breadth×height+length×height)

=2(7×5+5×3+7×3)=2(35+15+21)=2×71=142sq.cm
