Step-by-step explanation:
I just learned this in class lol
Find the area of all the sides.
This cubiod has 6 sides.
6 x 5 = 30
4 x 5 = 20
6 x 4 = 24
30 + 30 + 20 + 20 + 24 + 24 = 148
Thefore, the surface area of this cuboid is 148.
Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D
Answer:
B.
Perpendicular lines always intercept at a right angle (90 degrees).
1. 0.9
2. -20.4
3. 4.6
4. 1.6
Formula for the perimeter of a rectangle:
24 units ^2
The base runs from 3 to 7 so the base is 7-3 = 4 units
The height runs from 2 to 8 so the height is 8-2 = 6 units
The area is
A = bh
= 6*4 = 24 units ^2
its right
