Answer:
The answer to your question is 23.2 ft
Step-by-step explanation:
Data
length square pyramid = 10 ft
width of a cube = 6 ft
height of the pyramid = ?
The surface area is equal in both figures.
Formula
Surface area of a cube = 6a²
Surface area of a square pyramid = ab + al = l x l + (l x h) /2
Process
1.- Calculate the surface area of the cube
Ac = 6(6)² = 6(36)
= 216 ft²
2.- Substitute data in the square pyramid formula
Ap = (10 x 10) + (10h)/2
3.- Equal both areas
216 = 100 + 5h
- Solve for h
216 - 100 = 5h
116 = 5h
h = 116 / 5
- Result
h = 23.2 ft
Either c or d but most likely c
A= (1/2) b*h
h=3 sqrt3
A= (1/2)*6*3sqrt3
A= 9sqrt3 square inches
Answer:
y = 9
Step-by-step explanation:
m<1 + 2x = 180° because these angles are supplementary
61° + 2x° = 180°
2x = 180 - 61
2x = 119 divide both sides by 2
x = 59.5
Since f is parallel to s:
2x + (7y-2) = 180°
2×59.5 + 7y - 2 = 180
119 + 7y - 2 = 180
7y = 180 - 117
7y = 63 divide both sides by 7
y = 9
The answer is x=1/6
