Select the correct answer. What is the surface area of the victory podium shown here? Include all surfaces of the podium, includ
Leya [2.2K]

Answer:

Option C is correct.

Step-by-step explanation:

Given the dimension of the surfaces i.e length, width and height of podium. we have to calculate the surface area of the victory podium.

As Surface area of cuboid is 2(LW+WH+HL)

In the given figure, the upper cuboid has dimension

L=2.5 ft. , W=1.5 ft, H=1.5 ft

\text{Surface area=}2(2.5(1.5)+1.5(1.5)+1.5(2.5))=19.5ft^2

\text{Area of bottom face of upper cuboid=}L\timesW=2.5\times1.5=3.75ft^2

The upper face is occuring twice therefore it must be subtracted to find the area

Dimensions of lower podium are

L=7.5 ft. , W=1.5 ft, H=1.5 ft

\text{Surface area=}2(7.5(1.5)+1.5(1.5)+1.5(7.5))=49.5ft^2

Now, Surface area of podium included bottom is

19.5+49.5-3.75=65.25 square feet.

Hence, option C is correct.

Merle has an offer from a credit card issuer for a 0% APR for the first 60 days and a 23.19% APR afterwards, compounded daily. W
Andreyy89

To find the rate add 1 to the annual rate divided by 365 days raised to the number of days left in the year minus 1.

 r= (1 + 0.2319/365)^305 - 1

r = 0.2138

Now multiply by 100 for the percent:

0.2138 x 100  = 21.38%
