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:
The answer to your question is 6.- B 7.- D
Step-by-step explanation:
Data
Parallelogram ACFG
6.-
m∠GAC = 112°
m∠ACF = ?
Process
These angles are supplementary, they measure the same.
∠GAC + ∠ACF = 180
-Substitution
112 + ∠ACF = 180°
-Solve for ∠ACF
∠ACF = 180° - 112°
-Result
∠ACF = 68°
7.-
m∠AGF = 2a + 10
m∠ACF = a + 20
The angles ∠GAC and ACF are equal, they measure the same.
∠GAC = ∠ACF
-Substitution
a + 20 = 2a + 10
-Solve for a
a - 2a = 10 - 20
-Result
-a = -10
a = 10
-Find ∠AGF
∠AGF = 2(10) + 10
20 + 10
= 30°
