Answer:
The area of the cross section of the cube is 68 cm
Step-by-step explanation:
Volume of the cube is
561·5 cm
Given
a edge or side of the cube
so, cube root on both the side will be
a 8·25 cm
Cross section area of the cube is it depends where you cut the cube if cut the cube parallel and perpendicular to the faces then the cross sectional area will be a square whose length is the same as the length of the cube
Cross section area of the cube
cm
68 cm
Therefore , the area of the cross section of the cube is 68 cm
Answer:
The number of arrangements she made was:
2 small arrangements
3 medium arrangements
4 large arrangements
Step-by-step explanation:
There are 3 sizes of arrangement
Let r = roses
d = daisies
c = chrysanthemums
Each small arrangement contains one rose, four daisies, and four chrysanthemums.
r + 4d + 4c
Each medium arrangement contains two roses, four daisies, and five chrysanthemums.
2r + 4d + 5c
Each large arrangement contains four roses, six daisies, and six chrysanthemums.
4r + 6d + 6c
We are told that
One day, the florist noted that she used a total of 24 roses, 44 daisies, and 47 chrysanthemums in
Rearranging the equations,
Where s = small arrangements
m = medium arrangements
l = large arrangements
we have:
s + 2m + 4l = 24 ........Total number of roses
3s + 4m + 8l = 50 ....... Total number of daisies
3s + 6m + 6l = 48 ......... Total number of Chrysanthemums
From the above:
We can see that we have 3 equations and to solve it, we use Matrix method to solve this question because this is a 3 system (3 × 3) Matrices
I am unable to type the Matrices solution here, so please find it attached to this answer.
