To solve this problem you must divide the area of the floor by the area of the sticker, then you must apply the formula for calculate the area of a rectangle, which is:
A=lw
Where l is the length and w is the width.
Therefore, you have:
A=20x10/2x1
A=200/2
A=2x10^2/2x10^0
The answer is: 2x10^2/2x10^0

Answer:

V = 9.828 * 10^7 mm^3

a= 9.828 b = 7

9,827,000 mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3 * 3.9*10^2 * 2.1*10^2

We multiply the numbers out front and add the exponents (the powers of 10)

V = (1.2*3.9*2.1) * 10^(3+2+2)

V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left. Since there is not enough places add zeros

9,827,000 mm^3

In the figure below, the two triangular faces of the prism are fight triangles with sides of length 3, 4, and 5. The other three

The figure of the prism is attached below.

The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.

Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.

Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units

There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.

So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units

The Surface Area of the prism will be:

Surface Area = 2 (4) + 72 = 84 square units

Thus the correct answer is option A
