question:
How many cubes with side lengths of \dfrac12 \text{ cm} 2 1 cmstart fraction, 1, divided by, 2, end fraction, start text, space, c, m, end text does it take to fill the prism?
Step-by-step explanation:
81 cubes are needed to fill the prism
Step-by-step explanation:
Volume of prism = 3 cubic units
Side lengths of cube = 1/3
Therefore the volume of the cube is,
V = a³ (a = side of the cube)
V = 1/3 × 1/3 × 1/3
= ( 1/3 )³
= 1/27 cubic units
To find the number of cubes needed to fill the prism, we need to divide the volume of cube by volume of the prism.
Number of cubes to fill the prism= Volume of prism / Volume of cube
= 3÷1/27
=3×27/1
= 81
Therefore, 81 cubes are needed to fill the prism
Answer:
8
Step-by-step explanation:
It depends what mathematics you know
Perhaps the most basic way would be by approximation. You could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.
Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.
Try 8: 8*8*8=512.
Answer: -1.51, or it could be 4.09 < 5.6 (Im sorry if I get it wrong I just wanted to help)
Step-by-step explanation:
Answer:
Probability of selected sample is floral = 1 / 3
Step-by-step explanation:
Given:
Number of fabric sample = 6 sample
Number of floral sample from all samples = 2 samples
Find:
Probability of selected sample is floral
Computation:
Probability of a sample = Favorable outcome / Total outcomes
Probability of selected sample is floral = Number of floral sample / Number of fabric sample
Probability of selected sample is floral = 2 / 6
Probability of selected sample is floral = 1 / 3
Total gumballs= 6 yellow+ 5 green + 4 red
= 15 gumballs
Green gumballs=5
Other gumballs= 15-5= 10
Probability= Other non-green gumballs/Total gumballs
=10/15 = 2/3
Probability of not getting green gumball is 2/3 or 66.66666.... %
The ration is 2:3.
