Answer:

Surface area of the refrigerator is 864 in².

Step-by-step explanation:

Formula to calculate the surface area of a cube is,

Surface area = 6s²

Here, s = length of a side of the cube

If side length 's' = 12 inches

By substituting this value in the formula,

Surface area = 6(12)²

= 6 × 144

= 864 inch²

Therefore, surface area of the refrigerator is 864 in².

FrozenT [24]

Amount of blue dye mixed with one gallon of white paint= $\frac{3}{4}$

Amount needed for 8 gallons = $\frac{3}{4}\times8=6$ ounce

Amount of pink dye mixed with one gallon of white paint= $\frac{2}{3}$

Amount needed for 8 gallons = $\frac{2}{3}\times8= \frac{16}{3}$ ounces

So, total dye required = $6+\frac{16}{3}=\frac{18+16}{3}=\frac{34}{3}$

$11\frac{1}{3}$ ounces.

Hence, option C is correct.

Schach [20]

Area of wall = l×b

Length = 5m

Breadth = 20m

Area = 5×20

=100m²

Area of flex = side×side

= 2×2

= 4m²

Now no of flex that can be fitted = 100/4

= 25 flex

Answer:

C. 160,000

Step-by-step explanation:

Given that the measurements obtained for the interior dimensions of a rectangular box are 200 cm by 200 cm by 300 cm.

Also given that each of the three measurements has an error of at most 1 cm

COnsider the worst case where each dimension is increased by 1 cm

Then we measure the dimensions as 201 , 201 and 301

So volume would be measured as

$201*201*301\\= 12160701$ cubic cm

Actual volume of the box = $200*200*300\\=12000000$ cubic cm

Difference maximum possible = 160701 cubic cm

Out of the five options given option C is nearest to this value

So answer is

C. 160,000
