Answer:
3 boxes
Step-by-step explanation:
First, we find how many cubes are in each box, then we find how many boxes you need for 140 cubes.
<u>To find the number of cubes in a box we need to find the volume of the figure</u>
the top is 2 wide and 4 long so there are 8 cubes on each layer. Sense it is 8 cubes tall with 8 cubes on each layer the model has 8×8=64 cubes in each box.
<u>Now we divide then round up to find how many full boxes she needs to get 140 cubes or more.</u>
If 1 box has 64 cubes and she needs 140 cubes 140/64=2.187. Now we round up sense he can't buy a fraction of a box and the answer is: She needs 3 boxes
Answer:
A = 2500 + 2500 · 0.06 · 4 = 3100
Step-by-step explanation:
36/48=6/8=3/4 so 75% completed training
4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents
(8,6)...this means 8 lbs of potatoes cost $6
