Surface Area of a Closed Box

The surface area of a rectangular prism of dimensions x, y, and z is given by:

A = 2(xy + yx + xz)

The dimensions of a closed box (a rectangular prism) with dimensions x=3 cm, y=5 cm, and z=4 cm is:

A = 2(3*5 + 5*4 + 3*4)

Calculating:

A = 2(15 + 20 + 12)

A = 2(47)

A = 94 square cm

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
