Answer:
Planter 1 is 48 meters cubed
Planter 2 is 24 meters cubed
Total volume = 72
Step-by-step explanation:
The formula for the volume of a rectangular prism is length times width times height. So, 4*4*3. This equals 48. If the other planter is half the volume, divide 48 by 2 to get 24 meters cubed. To find the total area add both results to get a total of 72 meters cubed.
Answer:
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
