Answer:
40 marbles.
Step-by-step explanation:
Given:
Box A can hold 10 marbles.
Box B is double the height of Box A, four times the length of Box A, and half the width of box A.
Question asked:
How many marbles can Box B hold?
Solution:
Let volume of box A =
Let volume of box B =
Now, suppose:
Length of box A =
Breadth =
Height =
So, volume of box A,
As given, Box B is double the height of Box A, four times the length of Box A, and half the width of box A.
So, Length of box B =
Breadth =
Height =
Volume of box B, =
By dividing volume of box A with volume of box B:
By cross multiplication:
That means volume of box B is 4 times volume of box A;
∵ Box A can hold = 10 marbles
∴ Box B ( 4 times of box A ) can hold =
Therefore, Box B can hold 40 marbles.
The correct answer is B.
0.5(4x + 12)
2x + 6
