Answer:
The surface area of given cuboid is: 148 square centimeters
Step-by-step explanation:
Let
l = 5
w = 4
h = 6
The cuboid has 6 rectangular surfaces.
The surface area of a cuboid with height h, length l and width w is given by:
Putting the values
Hence,
The surface area of given cuboid is: 148 square centimeters
Answer:
32
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
All we need to do here is plug in the number 4 for the variable x. Wherever there's an x, kidnap it and replace it with a 4!
x = 4
Do the addition.
4 + 20 = 24
4 + 4 = 8
We can simplify this! What is 24 divided by 8?
24/8 = 3
The answer is 3!
Answer:
YX = 22
Step-by-step explanation:
Similar triangles. So,
Cross multiplication
45*(x+8) = 30 * (3x - 9)
45x + 360 = 90x - 270
360 = 90x - 270 - 45x
360 = 45x - 270
360 + 270 = 45x
45x = 630
x = 630/45
x = 14
YX = x +8 = 14 + 8 = 22
