Given:
Find the surface area.
Sol:
The total surface area is:
[tex]T=T_a+T_b+T_c+T_d+T_e+T_f[/tex]
Area is:
[tex]Area\text{ = Side 1 }\times\text{ Side 2}[/tex]
So,
[tex]\begin{gathered} T_a=10\times5=50 \\ \\ T_b=10\times12=120 \\ \\ T_c=12\times5=60 \\ \\ T_d=5\times10=50 \\ \\ T_e=10\times12=120 \\ \\ T_f=12\times5=60 \end{gathered}[/tex]
So total surface area is:
[tex]\begin{gathered} T=50+120+60+50+120+60 \\ \\ =460 \end{gathered}[/tex]
