so surface area minus top
so we have 4 sides and 2 of them are equal area
they area
legntht iems height
and
width times hiehgt
then the bottom is legntht iems width
so surface area is
2(lh)+2(wh)+(lw)
the surface are is the amount of material needed
L=6
W=3.5
H=3.5
subsitute
2(lh)+2(wh)+(lw)
2(6 times 3.5)+2(3.5 times 3.5)+(6 times 3.5)
2(21)+2(12.25)+(21)
42+24.5+21
87.5
87.5 in^2 of material
how much volume means
legnth times widh titme height
6 times 3.5 times 3.5
73.5 in^3
1. 87.5 in^2 of material
2. 73.5 in^3 is volume
