Answer 1

can u help me

Answer 2

plz

Answer 3

come back plz

Answer 4

L = 4
W = 5
H = 2

Surface Area:

SA = 2*(LW + WH + LH)
SA = 2*(4*5 + 5*2 + 4*2)
SA = 76 square meters

Volume:

V = L*W*H
V = 4*5*2
V = 40 cubic meters

To find the ratio of the surface area to the volume, you divide the surface area by the volume

SA/V = 76/40 = 1.9

so 1.9 is the answer
