Answer:
SA=94
Step-by-step explanation:
SA= 2(4*5) + 2(4*3) + 2(5*3)
SA=2(20) + 2(12) + 2(15)
SA=40 + 24 + 30
SA=94
The weight of galss cube with side 5 cm is 300 grams
<em><u>Solution:</u></em>
A glass cube is of side length 5 cm
Let us first find the volume of glass cube
<em><u>The volume of cube is given as:</u></em>
![volume = (side)^3\\\\volume =5^3 = 125](https://tex.z-dn.net/?f=volume%20%3D%20%28side%29%5E3%5C%5C%5C%5Cvolume%20%3D5%5E3%20%3D%20125)
Thus volume of cube is 125 ![cm^3](https://tex.z-dn.net/?f=cm%5E3)
Given that,
![1 cm^3 = 2\frac{2}{5} \text{ grams }\\\\1 cm^3 =\frac{12}{5} \text{ grams}](https://tex.z-dn.net/?f=1%20cm%5E3%20%3D%202%5Cfrac%7B2%7D%7B5%7D%20%5Ctext%7B%20grams%20%7D%5C%5C%5C%5C1%20cm%5E3%20%3D%5Cfrac%7B12%7D%7B5%7D%20%5Ctext%7B%20grams%7D)
So, weight of 125 cubic centimeter of glass cube is found by multiplying weight of 1 cubic centimeter of glass cube by 125
![\text{ Weight of 125 } cm^3 \text{ cube } = \text{ Weight of 1 } cm^3 \text{ cube } \times 125](https://tex.z-dn.net/?f=%5Ctext%7B%20Weight%20of%20125%20%7D%20cm%5E3%20%5Ctext%7B%20cube%20%7D%20%3D%20%5Ctext%7B%20Weight%20of%201%20%7D%20cm%5E3%20%5Ctext%7B%20cube%20%7D%20%5Ctimes%20125)
![\text{ Weight of 125 } cm^3 \text{ cube } = \frac{12}{5} \times 125 = 25 \times 12 = 300](https://tex.z-dn.net/?f=%5Ctext%7B%20Weight%20of%20125%20%7D%20cm%5E3%20%5Ctext%7B%20cube%20%7D%20%3D%20%5Cfrac%7B12%7D%7B5%7D%20%5Ctimes%20125%20%3D%2025%20%5Ctimes%2012%20%3D%20300)
Thus weight of galss cube with side 5 cm is 300 grams
Answer:
True
Step-by-step explanation:
In mathematics, a conic section (or just conic) is a curve obtained by intersecting a cone (more precisely, a right circular conical surface) with a plane. The point line and pair of intersecting lines are special types of conic sections.
