Question

acuboidboiled has length 6 CM breadth 5.5 cm and height 2.5 find its total surface area​

Answer 1

Answer:

$\large \bold\red{ T.S.A = 123.5 \: {cm}^{2} }$

Step-by-step explanation:

Given,

A cuboid having dimensions,

• Length, l = 6 cm
• Breadth, b = 5.5 cm
• Height, h = 2.5 cm

To find the Total Surface Area.

We know that,

$\large \boxed { \bold \purple{T.S.A = 2(lb + bh + hl)}}$

Therefore,

Putting the respective values,

We get,

$= > T.S.A =2( (6 \times 5.5 )+( 5.5 \times 2.5) + (2.5 \times 6)) \\ \\ = > T.S.A = 2( 33 + 13.75 + 15) \\ \\ = >T.S.A = 2 \times 61.75 \\ \\ = > \large \bold{ T.S.A = 123.5 \: {cm}^{2} }$

Answer 2

Answer:

123.5 cm²

Step-by-step explanation:

Length of a cuboid⇒6 cm

Breadth of the cuboid⇒5.5 cm

Height of the cuboid⇒2.5cm

Now we know that to find the Total Surface Area the formula is

                            ⇒2(L×B+B×H+H×L)

                           ⇒2(6×5.5+5.5×2.5+2.5×6)

                            ⇒2(33+13.75+15)

                            ⇒2(46.75+15)

                             ⇒2(61.75)

                              ⇒2×61.75

                               ⇒123.5 cm²

So, the Total Surface Area of a Cuboid is⇒123.5 cm²
