A box has a volume of 22 1/2 in³. Find the length of the box!
aliya0001 [1]

Answer:

Length = 2.823 in (to 3 decimal places)  

Step-by-step explanation:

assuming that the box is a cubic box:

volume of box = 22\frac{1}{2} in³ = 22.5 in³

volume = Length × Length × Length = (Length)³

∴ (Length)³ = 22.5

∴ Length = ∛(22.5)

using the calculator punch ∛(22.5), and the answer is:

∴ Length = 2.823 in (to 3 decimal places)

One thousand tonnes (1000 t, one t equals 10 cubed kg) of sand contains about a trillion (10 super 12) grains of sand. How many
Phantasy [73]

Answer with Step-by-step explanation:

Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)

Thus we have

1 mole of sand = 6.022\times 10^{23} sand particles

Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is

\frac{6.022\times 10^{23}}{10^{12}}=6.022\times 10^{11}

Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of 6.022\times 10^{11} trillion sand particles is

Mass=1000\times 6.022\times 10^{11}=6.022\times 10^{14}tonnes

Part 2)

Since it is given that volume of 1 sand particle is 1.0mm^{3} thus the volume of 1 mole of sand is volume of 6.022\times 10^{23} sand particles

Thus volume of 1 mole is V=1.00\times 10^{-18}km^{3}\times 6.022\times 10^{23}=6.022\times 10^{5}km^{3}

Now since the Area of united states is A=3.6\times 10^{6}mile^{2}=5.8\times 10^{6}km^{2}

Thus the depth of the sand pile is

Depth=\frac{Volume}{Area}=\frac{6.022\times 10^5}{5.8\times 10^6}=0.10387km=103.8meters

RUDIKE [14]

Answer: 315 miles

Step-by-step explanation:

let onward speed = x mph, then distance = 7x

return speed = (x+18) mph, (same) distance = 5(x+18)

equating the two,

7x = 5(x+18)

2x = 90 ==> x = 45 mph

so distance = 7*45 = 315 miles
