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:
A and C are the right answers
Step-by-step explanation:
Top row only
3 out of the 12 squares are shaded in therefore 3/12 which you can simplify into 1/4
Left column only
3 out of the 6 squares are shaded in therefore 3/6 which you can simplify into 1/2

Answer:
19 cm
Step-by-step explanation:
The perimeter is 51cm
The side lengths are x, x+2, and x+4
To find perimeter, we add all the side lengths.
Therefore, the equation we would use is the following:
x + x+2 + x+ 4 = 51
Then we solve for x
3x + 6= 51
Subtract 6 on both sides
3x = 45
divide by 3
x=15
Now, x is the smallest side, and we are trying to find the longest side,
So we plug in x for the longest length:
(15) + 4= 19
19cm is the longest side of the triangle.
Answer: 16 ounce
Step-by-step explanation:
16 ounce is 1.17 per ounce but 7 ounce is 1.19 per ounce in real life the bigger is usually a better deal anyway
