What is the volume of two cubes with a side length of 1/2 foot? V = s^3, where s is the side length. 1/2 ft^3
1/4 ft^3
1/8 ft^3
1/9 ft^3

So the answer should be 1/4.

Step-by-step explanation:

so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two  cubes so you would multiply that by two creating 2*1/2*1/2*1/2

Hope this helps :)

Please tell me if not.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

i think it would be 42cm
