Answer:
A = 24
Step-by-step explanation:
We can see that the face of the given rectangular prism shows the width 4 and the height of 6. If we cut the figure at any point along the length 20, such that the cross section is parallel to the face, the cross section, which occurs at x length, will always have the same dimensions, that are 4 and 6.
So the area of the cross section which is parallel to the face of the given rectangular prism is given by:
A = 6 × 4
A = 24
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²
a. When v = c, then v^2 = c^2. The fraction v^2/c^2 becomes 1. The inside of the root is 1 - 1 which equals zero. Square root of zero is zero, and zero times L0, no matter what value L0 has, is zero. Therefore, when v = c, the left side equals zero.
b. When v = 0, and c is positive, v/c = v^2/c^2 = 0. By subtracting v^2/c^2, which is zero for v = 0, from 1, you get 1. Square root of 1 is 1. Then you multiply that by L0 to get L0. The greatest possible value of the left expression is L0.
