B. 25, 38, 13
These 3 will not form a triangle because the sum of the shorter sides must be greater than the longest side.
25 + 13 = 38 which is not greater than 38
Answer:
calculate the volume of a triangular prism, the formula is:
V = 0.5 X b X a X h.
Answer:
93
Step-by-step explanation:
x = 4, y = 5
3(4x + 3y)
= 3(4(4) + 3(5))
= 3(16 + 15)
= 3(31)
= 93
Answer:
<u>L.A. = 80 + 16√13</u>
Step-by-step explanation:
the lateral area is the area of the vertical faces.
So, for the given prism = The sum of the area of the vertical rectangles.
= height * perimeter of the right triangle.
The hypotenuse of the right triangle = 
So, the sides of the triangle are 4 , 6 and 2√13
The perimeter of the right triangle = 4 + 6 + 2√13 = 10 + 2√13
Height = 8
The lateral area for the prism = 8 * ( 10 + 2√13 ) = 80 + 16√13
