A rectangular gift box measures 8 inches by 10 inches by 3 inches. what is the surface area?

2 answers:

8 0

8 x 10 = 80 inches squared (one side)
3 x 8 = 24 inches squared (one side)
3 x 10 = 30 inches squared (one side)
80 + 24 + 30 = 134 inches squared (three sides)
Double that for all 6 sides. 2 x 134 = 268 square inches.
The answer is D.

SA = 2(wl+hl+hw)

SA = 2((3)(10)+(8)(10)+(8)(3))

Multiply:

SA = 2(30 + 80 + 24)

Add:

SA = 2(134)

Multiply:

SA = 268

Y_Kistochka [10]

Answer:

h = 147 - 16t^2.

Step-by-step explanation:

Use the following equation of motion

h = ut + 1/2 gt^2 where h = height, u = initial velocity , g = acceleration due to gravity and t = the time.

So here we have:

h = 14t + 1/2 * -32 * t^2

h = 14t - 16t^2

Wittaler [7]

Answer:

Step-by-step explanation:

A soccer field is a rectangle 60 meters wide and 110 meters long. The coach asks players to run from one corner of the grass field to the opposite corner. The path from one corner of the grass field to the opposite corner is the diagonal of the rectangular field.

The width, the length and the diagonal of the rectangular field form right triangle. By the Pythagorean theorem,

$\text{Diagonal}^2=\text{Width}^2+\text{Length}^2\\ \\\text{Diagonal}^2=60^2+110^2\\ \\\text{Diagonal}^2=3,600+12,100\\ \\\text{Diagonal}^2=15,700\\ \\\text{Diagonal}=\sqrt{15,700}\approx 125\text{ yd}$
