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).
For every 10hrs of training you have 200$ increase.
Then for each hour, it will be $20.
Answer:
(9x+10)(9x+10)
Step-by-step explanation:
Factor 81x^2+180x+100
81x^2+180x+100
=(9x+10)(9x+10)
Answer:
c
Step-by-step explanation:
the answer is c because the kitten had gained 2 1/8 ounces and you would know that because 2 plus 3 3/8 is 5 3/8 and then add 1/8 which would be 4/8 so that 1/2
