Answer:

The number of boys is 162. The percentage for girls is 55% and for boys is 45%.

<u>Step-by-step explanation:</u>

The formula to find percentage p=\frac{x}{y} ×100.

where x is the part value for that percentage is to be found.

y is the total value.

For girls,

p=\frac{198}{360} ×100.

Percentage for girls p=55%.

For boys,

The Number of boys = 360 - 198.

Boys = 162.

p=\frac{162}{360} ×100.

Percentage for boys p=45%.

solniwko [45]

Answer:

The total surface area of all 6 prisms is 6336 in^2.

Step-by-step explanation:

Let's find the surface area of ONE prism and then multiply that result by 6 to obtain the final answer.

One prism:

The area of the two 13 in by 26 in rectangular tabs is 2(13 in)(26 in), or 676 in^2 (subtotal);

The area of the two triangles of base 10 in and height 12 in is 2([1/2][10 in][12 in], or 120 in^2; and, finally,

The area of the 10 in by 26 in base is 260 in^2.

The total surface area of ONE prism is thus:

676 in^2 + 120 in^2 + 260 in^2, or 1056 in^2.

Now, because there are 6 of these prisms, multiply this last result by 6:

6(1056 in^2) = 6336 in^2.

The total surface area of all 6 prisms is 6336 in^2.
