What is the surface area of this rectangular prism?

Mathematics

Lesechka [4]3 years ago

Answer:

160cm^2

Step-by-step explanation:

So the surface area is basicly the sum of all the areas of the rectangles in this prism.

So the formula can be written as  2(wl + hl+hw).

The w stands for width, the h stands for height, and the l stands for length.

5cm is the width, 10 cm is the length, and 2 cm is the height.

So inserting all those values for the variabls the formula now looks like this.

2((5)(10)+(2)(10)+(2)(5)).

So 5*10 is <u><em>50</em></u>

2*10 is <u><em>20</em></u>

2*5 is <em><u>10</u></em>

So adding all that up we get 80.

Then multiplyong that by 2 we get 160cm^2.

Answer:

x= 10°

Step-by-step explanation:

BWN = BRN (W=R)

56+ (5x-16) +90 =180 {triangle BNW} [angles in a triangle add up to 180] ( properties of a kite)

5x = 180 - (56 + 90 - 16)

5x = 180 - 130

5x = 50

x =50/5

x = 10°
