We have a rectangular prism, in order to find the surface area we will use the next formula
[tex]SA=2lw+2lh+2wh[/tex]where
l is the length
w is the width
h is the height
in our case
l=6m
w=3m
h=10m
then we substitute the values
[tex]SA=2(6)(3)+2(6)(10)+2(3)(10)[/tex][tex]SA=216m^2[/tex]the surface area of the figure is 216m^2
