Question

What is the total surface area? After that, add and then put in subscript. Label the net (For Example look at the picture)

Answer 1

Given:

Find the surface area.

Sol:

The total surface area is:

`T=T_a+T_b+T_c+T_d+T_e+T_f`

Area is:

`Area\text{ = Side 1 }*\text{ Side 2}`

So,

`\begin{gathered} T_a=10*5=50 \\ \\ T_b=10*12=120 \\ \\ T_c=12*5=60 \\ \\ T_d=5*10=50 \\ \\ T_e=10*12=120 \\ \\ T_f=12*5=60 \end{gathered}`

So total surface area is:

`\begin{gathered} T=50+120+60+50+120+60 \\ \\ =460 \end{gathered}`
