Answer:
768 m^2
Step-by-step explanation:
<u>Separate the shapes</u>
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
<u>Calculate</u>
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2
Answer:
I got you. The answer is 42
Step-by-step explanation:
First, you find the area of the big rectangle as if the missing piece wasn't there. So do 5 x 10 which is 50 cm. Then you calculate the area of the second rectangle (aka the missing piece). The dimensions of the missing piece is 2 x 4. 2 x 4 = 8, so the missing piece has an area of 8 cm. Finally, you subtract the area of the missing piece from the area of the shape.
50 - 8 = 42
The area of the shape is 42 cm.
Hope this helps
Answer:
252 cubic cm
Step-by-step explanation:
V = (l x w x h ) / 3
V = (6 cm x 9 cm x 14cm) / 3
V = 756/3 = 252 cubic cm
In Scientific notation 6,000,000 = 6 x 10^6
Answer:
24
Step-by-step explanation:
If you know that the area for the large rectangle is 216 and you are given the width then you can find the length. All you do is 216/9 and you get 24. At the smaller rectangle the width is 3, so you will divide 3 from the big rectangle to find the length of the smaller rectangle. 24/3=8. So 8 times 3 is 24 and that is your answer.
