Answer:
270 first question's answer
Step-by-step explanation:
Solution at attachment box
Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2
=432+240+360
=1032
Surface of the 1 cube =2x2x2 = 8
Surface of the all cubes = 8x270 = 2160
First, you divide 4 by 2 before you subtract them by 5 using BODMAS, or BIDMAS.
4 ÷ 2 = 2
5 - 2 = 3
3 is your answer
48 + 2x = 180
- 48 - 48
----------------------------
2x = 132

2
x = 66
The mean is 29.72, the median is 30.4, the mode is 40.3, 38.0, 29.0, 30.4, 10.9
The distance between two numbers
![x](https://tex.z-dn.net/?f=x)
and
![y](https://tex.z-dn.net/?f=y)
is given by the absolute value of their difference,
![|x-y|](https://tex.z-dn.net/?f=%7Cx-y%7C)
.
So the distance on the number line between
![12](https://tex.z-dn.net/?f=12)
and
![-5](https://tex.z-dn.net/?f=-5)
is
