Answer:
52 ft²
Step-by-step explanation:
Given :
Dimension : 2 by 3 by 4
Surface area of a rectangular prism :
2(wl + lh + wh)
Length = l
Width = w
Height = h
Surface Area = 2[(2*3)+(2*4)+(4*3)]
Surfave Area = 2[6+8+12]
Surface Area = 2(26)
Surface Area = 52 ft²
Answer:
x° =121°
Step-by-step explanation:
The inside angles of a triangle together must equal 180°. Therefore, 58° + 63° + n° = 180° if n equals the third angle inside the triangle. So,
180°-(58°+63°)=n°
180° - 121° = n°
59° = n°
Since the outside angle x and 59° must also equal 180°,
180° - 59° = x°
121° = x°
You can also find the exterior angle without finding the interior by adding the two other interior angles together.
58°+63°=x°
121°=x°
