This whole problem rests on one thing:
Do you know the formula for the volume of this kind of shape ?
If you do, then the problem is easy. If you don't, then it's impossible.
This is the shape of a book, an ice cube, a brick, or a slab.
The volume is always
(length) x (width) x (height) (in any order) .
They all have to be in the same unit, and then the volume
is in the cubic-(...) of that unit.
In this picture, there's a tiny hiccup with the units ... the length and
the width are in meters, but the height is in centimeters, so you need
to change that one to meters before you can multiply them.
Notice right above the picture, it reminds you that
(1 meter = 100 centimeters) .
So the height of the slab (10 cm) is the same as 0.1 meter.
Now you have all 3 of the dimensions in meters, so you're
ready to multiply them and get the volume.
Volume = (length) x (width) x (height)
= ( 8 m ) x ( 6 m ) x ( 0.1 m )
= 4.8 cubic meters .
Question:
Does Meg have enough concrete to make the slab
with the dimensions shown ?
Answer: Yes .
Explanation:
Meg mixed 5 cubic meters of concrete.
She needs 4.8 cubic meters to pour the floor with those dimensions.
She has enough concrete to do the job.
All she needs is the whole football team to come over and help her
pour, smooth, and finish it. Concrete is hard hard work !
Answer:
Step-by-step explanation:
basic facts:
34% is the same as 34/100
the word 'of' in maths also means multiply
34% of 600 is the same as 34/100 * 600, which is 204
a quarter of 204 is the same as 1/4*204, which is 51
hopefully this helps!!
Answer:
well I know one you can try SOLVEITNOW
you can also try MICROSOFT MATH SOLVER
or CYMATH-MATH PROBLEMS SOLVER
Volume of a cylinder is
h. This is basically the area of a circle multiplied by the height. You can think of it as congruent circles being stacked on top of each other to create a cylinder. With the given information, all we have to do is substitute the values into the variables
V =
h.
V =
x30
V =
x 169 x 30 =
5070
Hope this helps!
(btw if it asks for "exact" anything, leave the pi. Pi is the ratio of the circumference to its diameter, so not every circle will have a pi of 3.14.)
