Question

# Find the Total surface area if the given dimensions are 6 cm,4cm, and 5 cm.

- 164 cm
^{2} - 120 cm
^{2} - 148 cm
^{2} - 134 cm
^{2}

^{2}^{2}^{2}^{2}Hint:

**Hint:- **We have given three different dimensions ,

Total Surface Area(TSA) of cuboid = 2[ lb + bh + hl ]

where

l → length of the cuboid

b → breadth of the cuboid

h → height of the cuboid

## The correct answer is: 148 cm^{2}

### We will calculate the total surface area of a cuboid by using the following formula:

The dimensions of the given cuboid:

Length, l = 4 cm

Breadth, b = 5 cm

Height, h = 6 cm

By using the above formula of the total surface area of the cuboid, we get

The total surface area of the given cuboid is,

=

=

=

=

= 148 cm^{2}

Thus, the total surface area of a cuboid of dimensions 6 cm, 4 cm & 5 cm is 148 cm².

The correct option is C)148 cm².

Note:- In some examples it may be given the surface area and any two dimensions , then we have to adjust the formula such a that we will be able to find out the required value . For eg- If area , length and breadth is given the formula for height becomes

^{2}

Thus, the total surface area of a cuboid of dimensions 6 cm, 4 cm & 5 cm is 148 cm².

The correct option is C)148 cm².

Note:- In some examples it may be given the surface area and any two dimensions , then we have to adjust the formula such a that we will be able to find out the required value . For eg- If area , length and breadth is given the formula for height becomes
