Which could be the dimensions of a rectangular prism whose surface area is less than 160 square feet? Select two options.
x
8 feet by 4 feet by 3 feet
07 feet by 6 feet by 4 feet
3 feet by 7 feet by 8 feet
3 feet by 6 feet by 7 feet
3 feet by 5 feet by 7 feet

a,e

Step-by-step explanation:

let length=l

width=w

height=h

surface area=2(l+w)×h+2×l×w

=2[lh+wh+lw]

2(8×4+4×3+8×3)=2(32+12+24)=2×68=136<160

2(7×6+6×4+7×4)=2(42+24+28)=2×94=188>160

2(3×7+7×8+3×8)=2(21+56+24)=2(101)=202>160

2(3×6+6×7+3×7)=2(18+42+21)=2(81)=162>160

2(3×5+5×7+3×7)=2(15+35+21)=2(71)=154<160

correct answer is b. 27/8

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
