Answer:
592 in²
Step-by-step explanation:
Given
Length of the box L = 12 inches
Width W = 8 inches
height H = 10inches
Required
Surface Area of the box
Surface area of the rectangular boss = 2(LW + LH + WH)
Substitute the given values
Surface area = 2(12(8)+12(10)+8(10))
Surface Area = 2(96+120+80)
Surface Area = 2(96+200)
Surface area = 2(296)
Surface area = 592 in²
Hence 592 in² of wood would be needed by Mitchell to build the box

Answer:
24.6 % decrease
Step-by-step explanation:
Let x be the original temperature
Increase by 25%
x + .25x
1.25x
Decrease by 40%
The amount decreased is
(1.25x) *.40
.496x
Subtract that from 1.25x
1.25x - .496x
.754x
We need to find the percent decrease
1 - .754 = .246
24.6 % decrease
5/4 or 1 1/4
Solve -2 + 3/4= 1.25
Maybe rate of change? Im not sure.
I would assume so since it is a repeating decimal.
