Answer:
Surface area of prism=
Step-by-step explanation:
We are given that surface area of rectangular prism=
We have to write an expression that represents the surface area of prism.
Base of prism is made from length and width
Perimeter of base =2(l+w)
Area of base=lw=Area of top
Surface area of prism=Perimeter of base multiply by height+2 area of base
Because area of base and area of top are equal.
Surface area of prism=Ph+2B=2(l+w)h+2(lw)
Answer:
<em>800÷100 = 8</em>
<em>65×8=520</em>
another way:
<em>100%-65%=35%</em>
<em>35% = 0.35</em>
<em>800×0.35= 280</em>
<em>800-280=</em>520
another way:
<em>65% = 0.65</em>
<em>0.65×800=</em>520
Hope it helped! :)
