Ho do you get the Surface Area of this shape?

Answers

Answer 1

Answer: This solid object contains 8 sides.

The side that is facing you has a surface area:

$64f{ t }^( 2 )+84f{ t }^( 2 )=148f{ t }^( 2 )$

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

$84f{ t }^( 2 )$

The side to your right has a surface area:

$84f{ t }^( 2 )$

The side to your left has a surface area:

$48f{ t }^( 2 )$

The side to your top left has a surface area:

$48f{ t }^( 2 )$

The side beside the side to the top left has a surface area:

$36f{ t }^( 2 )$

The side at the very top has a surface area:

$36f{ t }^( 2 )$

Combined, the surface area is:

$S=2\cdot 148f{ t }^( 2 )+2\cdot 84f{ t }^( 2 )+2\cdot 48f{ t }^( 2 )+2\cdot 36f{ t }^( 2 )$

$\n \n =296f{ t }^( 2 )+168f{ t }^( 2 )+96f{ t }^( 2 )+72f{ t }^( 2 )\n \n =632f{ t }^( 2 )$

Therefore the answer is: C

Work out the area of a triangle of base 12cm and height 7cm

Answers

The area of ANY triangle is (1/2) x (its base) x (its height).

Put in the numbers you know, and the area is (1/2) x (12cm) x (7cm) .

I know you can handle it from that point.

the answer of your question is A=42cm2

Claire has 3/2 liters of water. She pours the water equally into 6 glasses. How much water is in each glass?

Answers

3/2 equally in 6 glasses is : 3/2 x 1/6 = 1/4

So she has 1.5 liters to split between 6 glasses.

1.5 / 6 = 0.25

Hence 250Ml in each glass.

Could you please answer the question in the attachment please?

Answers

For part (a), we know that 6/60 pupils wear glasses. We also know that there are 360 degrees in the pie chart. So the angles for people who wear glasses must be (6/60)*360. 6/60 simplifies to 1/10, and a tenth of 360 equals 36. So the angle must be 36 degrees. To find the other angle, simply subtract 36 from 360 degrees to get 324 degrees.
For part (b), it is not possible to tell because all 6 pupils who wear glasses could be girls, they could all be boys, some girls and some boys, etc. We cannot know which one it is, given only that much information.
Hope this helps!
