Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
![V = \frac{a^2h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7Ba%5E2h%7D%7B3%7D)
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
![V = \frac{18^2\times 12}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B18%5E2%5Ctimes%2012%7D%7B3%7D)
![= \frac{324\times 12}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B324%5Ctimes%2012%7D%7B3%7D)
![=\frac{3888}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3888%7D%7B3%7D)
cube cm.
⇒ First option is correct.
We will solve this by suing simultaneous equations,
⇒ 5s + 3j = 87
4s + 2j = 64
Multiply the first equation with 4 and the second one with 5, this is to get one of the values equal so that we can cancel them out,
⇒ (5s + 3j = 87) × 4
(4s + 2j = 64) × 5
∴ ⇒ 20s + 12j = 348
20s + 10j = 320
Subtract both the equations. This is how your result (after subtraction) should look like,
⇒ 2j = 28
∴ ⇒ j = $14
Now replace the value of 'j' in one of the original equations,
⇒ 4s + 2(14) = 64
⇒ 4s + 28 = 64
⇒ 4s = 64 - 28
⇒ 4s = 36
∴ ⇒ s = $9
Therefore, one pair of jeans cost $14 and a shirt costs $9
