Answer:

The surface area of Rectangular prism is 358 \ cm^2.

Step-by-step explanation:

Given:

Length of the rectangular prism = 7 cm

Width of the rectangular prism = 5 cm

Height of the rectangular prism = 12 cm

we need to find the surface area of rectangular prism.

Solution:

the surface area of rectangular prism is equal to 2 times sum of length times width and width times height and length times height.

framing in equation form we get;

the surface area of rectangular prism = 2(l\times w+w\times h+h\times l)

the surface area of rectangular prism = 2(7\times5+5\times12+12\times7) = 2(35+60+84) = 2\times179 = 358\ cm^2

Hence The surface area of Rectangular prism is 358 \ cm^2.

A cell phone cost $210 a battery charger costs $15 and batteries cost $5 .what is the sales tax and total price for purchasing t
Savatey [412]

The total price with sales tax is $ 246.1

<h3><u>Solution:</u></h3>

Cost of cellphone = $ 210

Cost of battery charger = $ 15

Cost of batteries = $ 5

So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries

Total cost = 210 + 15 + 5 = $ 230

Given that sales tax is 7%

sales tax = 7% of total cost

sales tax = 7 % of 230

\text {sales tax }=\frac{7}{100} \times 230=16.1

Total cost including sales tax = 230 + 16.1 = $ 246.1

Thus the total price with sales tax is $ 246.1
