cube is 5cm! Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?

Answer:

\Large \boxed{\sf 70.71 \  cm^2}

Step-by-step explanation:

Jackson had previously painted 6 faces of the cube.

The unpainted faces are the 2 faces inside the cube that is made when the cube is cut.

Area of the unpainted section is required.

The 2 faces are rectangles

2 \times (5 \times 7.071)=70.71 \ \sf cm^2

A rectangular conatainer with a square base is 2/3 full of water. This water is used to fill some small containers how many smal
vivado [14]

Answer:

5 small containers will be  required and used.

This water is used to fill four and half  small containers exactly.

4.5 small containers

Step-by-step explanation:

The rectangular container has dimensions 12*12*45 cm  and the small container has dimensions 6*5*8 cm

The rectangular container with a square base is 2/3 full of water.The height is used up to 45*2/3= 7.5 cm

The volume of the water in the rectangular container with a square base is

12*12*7.5= 1080 cm³

The volume of the water in the smaller container is

6*5*8= 240 cm³

Number of smaller containers required = Volume of large container / Volume of smaller container

Number of smaller containers required =1080 cm³/240 cm³= 4.5

This water is used to fill four and half  small containers exactly.

Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. Write your answer in terms of pi, and be su
Ksju [112]

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

Area= 2\pi r(r+h)

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

Area= 2\pi *4(4+3)

Area= 2\pi *4(7)

Area= 2\pi *28

Area= 56\pi

Hence final answer is

Area= 56\pi square ft

What is the surface area of the cube?
lorasvet [3.4K]
A cube has 6 sides, and each side has the area of 16 (since 4 times 4 is 16) so if you multiply 16 and 6 you get 96 mm2 as the surface area.
