We know, 1 yard=3 feet.
1 feet =12 inches.
Therefore, 1 yard in inches is,
Hence, 3 yards in inches is.,
Therefore, 3 yards is greater than 107 inches.
Total volume is volumes of both square pyramids.
Volume of a tetrahedron is 1/3 times corresponding prism, and a square pyramid has two tetrahedrons.
Thus, volume of on square pyramid:
Since there are two of them, total volume is:
$\boxed{\frac{2a^2b}{3}}$
Answer:
120 and 144
Step-by-step explanation:
Keep adding 24 to 96
Answer: 15
Step-by-step explanation:
<span>4x + 2y = 4
6x - 8 = -2y
Both equations are divisible by 2, so divide both sides of both equations by 2.
</span><span>2x + y = 2
3x - 4 = -y
Since the second equation has -y on one side, we can multiply both sides by -1 to solve for y.
y = -3x + 4
Now we substitute y of the first equation with -3x + 4.
This is the substitution method.
2x + y = 2
2x - 3x + 4 = 2
-x + 4 = 2
-x = -2
x = 2
Now we substitute 2 for x in the first original equation and solve for y.
4x + 2y = 4
4(2) + 2y = 4
8 + 2y = 4
2y = -4
y = -2
The solution is x = 2 and y = -2
