3. Surface Area Of
Cube And Cuboid

4. What Is Surface?
WHAT IS SURFACE
AREA?
Area occupied by the surface called
surface area.
1
2 5
The uppermost or exposed portion of any object.

5. Surface area of cube and cuboid
Difference Between Cube And Cuboid
CUBE
 Cube is a shape having six surface,
all the surface of the cube are
square in shape.
CUBOID
 Cuboid is also a shape having six
surface, but all the surface are
rectangular and only opposite
surface are equal to each other.

6. Total surface area of cube
l
Surface area of square = l * l = l2
Cube has 6 sides,
So, total surface area of a cube = l2 + l2 + l2 + l2 + l2 + l2
=6 l2
EXAMPLE: Find the total surface area of Cube taking length as 2cm?
T.S.A.=6(l)2
=6(2)2
=6*4
=24
l

7. 2. Suppose a cube having a length 5cm. Find out the surface
area of that cube.
Solution: T.S.A. = 6l2
Surface area of cube =6(5)^2
=6*25
=150cm2

8. Total surface area of cuboid
The sum of the area of the six rectangle is:
Area of rectangle 1 = ( l*h)
+
Area of rectangle 2 = ( l*b)
+
Area of rectangle 3 = ( l*h)
+
Area of rectangle 4 = (l*b)
+
Area of rectangle 5 = (b*h)
+
Area of rectangle 6 = (b*h)
= 2 ( l * b ) + 2 ( b* h) + 2 ( l * h )
=2 ( lb + bh + hl )
