Answer:
Equation
Step-by-step explanation:
Answer:
The total surface area of the cube, including the bottom is
22 m squared.
Step-by-step explanation:
a) Data and Calculations:
Side length = 3 m
Side height = 2 m
Side width = 1 m
The total surface area of the cube, including the bottom is given by the formula, 2lw+2lh+2hw), where l = length, w = width, and h = height.
This can also be rewritten as:
2(l*w + l*h + h*w)
= 2 (3*1 + 3*2 + 2*1)
= 2 (3 + 6 + 2)
= 2 (11)
= 22
b) Ernst should know that the surface area of a cube is the sum of the areas of all faces (or surfaces) because it is a 3D shape. Since the cuboid has 6 rectangular faces, Ernest can determine the surface area by adding the areas of all 6 faces or surfaces. Similarly, he can label the length as (l), width as (w), and height as (h) and use the formula, SA=2lw+2lh+2hw, to find the surface area. This formula can also be rewritten as 2(l*w + l*h + h*w).
Answer:
the answer is -89
Step-by-step explanation:
Answer:
0.65
Step-by-step explanation:
When we have a finite number of events
with its corresponding probabilities
with
then the expected value of the distribution is given by
In our case, we have
with probabilities
So, the expected value is
E = 0*0.58+1*0.24+2*0.13+3*0.05 = 0.65
