I am not sure but I would say either step 2 or 4 but I am not 100% sure I hope you do well. Good Luck:)
Negative 45 or -45 because different signs with multiplication are always negative
True, -4 seems bigger because 4 is bigger than 3 but it's negative and is further away from 0
Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
