I don't know how to find the surface area of this, please help.

900 m^2

Step-by-step explanation:

Find 3 different areas and double them.

The triangle becomes a rectangle because of this.

15 x 16 = 240

17 x 10 x 2 = 340

16 x 10 x 2 = 320

Add all.

240 + 340 + 320 = 900

it would be 6xy and -16xy.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
