Area of a triangle=1/2(base x height)
Area=72, Base=8, Height=2x-3
Plug it in.
72=1/2(8 x (2x-3))
72=1/2(16x-24)
72=8x-12
84=8x
x=10.5
586/10 -> 293/5 -> 58 3/5
A. 1/2 (2 pints)
B. 1/4 (4 quarts)
C. 1/8 (8 pints)
D. B (1/8)
1/2 x 1/4 = 1/8
Glad to Help!
Lateral area: AL = 4 * s * h
624 = 4 * s * 13
624 = 52 s
s = 624 : 52
s = 12 cm
The surface area of the prism:
A = 2 ·12² + 624
A = 2 · 144 + 624 = 288 + 624 =912 cm²
The volume:
V = a² · h = 12² · 13 = 144 · 13 = 1,872 cm³
Answer:
1. The surface area is equal to 912 cm².
2. The volume is equal to 1,872 cm³.
