Answer:
23 in
Step-by-step explanation:
Volume of a Cube: V = a³
Step 1: Define
V = 12,167 in³
a = ?
Step 2: Solve for side length <em>a</em>
- <u>Substitute:</u> 12,167 = a³
- <u>Cube root both sides:</u> 23 = a
- <u>Rewrite:</u> a = 23
Step 3: Check
<em>Plug in a to verify it's a solution.</em>
- <u>Substitute: </u>V = (23 in)³
- <u>Evaluate:</u> V = 12,167 in³
Length(l)= 2w+6
Width(w)= w
Area(A)= 140 m²
Area= l*w
140 = l*w
140= (2w+6)w
140= 2w²+6w( divide each side by 2)
70= w²+3w
w²+3w -70= 0
(^^^^^^Factor out expression)
(w-7)(w+10)= 0 (set each expression equal to zero and use the positive answer as the value for "w"(because a negative width is impossible))
w-7=0
w=7m
w+10=0
w= -10m (Impossible for a physical measurement to negative: therefore This "w" value is incorrect)
Use w=7 to find "l"
l= 2w+6
l=2(7)+6
l=14+6
l=20 m
Answer:
The dimensions of a rectangle are length and by width. For this rectangle the dimensions are 20 meters by 7 meters.
(width= 7 meters)
(length= 20 meters)
