Answer:
x = 9
Step-by-step explanation:
8/12 = 6/x
We can use cross products
8*x = 12*6
8x = 72
Divide by 8
8x/8 = 72/8
x = 9
Answer:
the volume is 1176 cm^3
Step-by-step explanation:
you can divide the bricks into two shapes, find their volumes and add them back together:
1st brick shape: 21 * 6 * 6 = 756 cm^3
2nd brick shape: 10 * 7 * 6 = 420 cm^3
now add them and you get 1176 cm^3 per identical brick as their volume, you just have to multiply the height, length and width that you know makes up a simpler shape

Answer:
48 sq inches
Step-by-step explanation:
Given that,
Ribbon used around a bulletin broard is 28 inches
The length of her board is 6 inches
Let B is breadth of her board. 28 inches is perimeter. The perimeter of rectangle is given by :
P = 2(L+B)
28=2(6+B)
14=6+B
B=8 inches
The area of a rectangle is given by :
A = L×B
A = 8×6
A=48 sq inches
So, the area of her board is 48 sq inches
