A rectangular prism has dimensions of 2 cm by 2 cm by 5 cm. What is the surface area? Explain or show your reasoning?

The dimensions are; 2cm, 2cm, 5cm respectively.
i.e ;
l = 2cm
b = 2cm
h = 5cm
SA of rectangular prism = 2(lb + bh + hl)
Put values.
SA = 2(2×2 + 2×5 + 5×2)
= 2× 24

21, i'm pretty sure it's right lol

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
