Question

PLEASE HELP I'M SORRY FOR A LOT OF QUESTIONS but I need help ​

Answer 1

Answer:

Hello! answer: 268 square meters

Step-by-step explanation:

To find the total surface area you find the area of each face then add them up so...

10 × 3 = 30

10 × 3 = 30

8 × 3 = 24

8 × 3 = 24

10 × 8 = 80

10 × 8 = 80

Now that I found the area for each face I will just add them up so...

30 + 30 + 24 + 24 + 80 + 80 = 268 therefore the area is 268 square meters Hope that helps!

Answer 2

Answer :

$\large\mathrm {\boxed{ \boxed{268 \: \: m {}^{2} }}}$

Solution :

The above pieces will form a cuboid, having dimensions :

$\mathrm{\longrightarrow length = 10 \: m}$

$\mathrm{\longrightarrow width = 8 \: m}$

$\mathrm{\longrightarrow height = 3 \: m}$

We know that Surface area of Cuboid is :

$\large \longmapsto \mathrm{{2(lw + wh + lh)}}$

Let's solve,

$\longrightarrow2[(10 \times 8) + (8 \times 3) + (10 \times 3)]$

$\longrightarrow2[80 + 24 + 30]$

$\longrightarrow2 \times 134$

$\longrightarrow268 \: m {}^{2}$
