1431 since for the top one you multiply 18 by 2 by 3 and then multiply 7 by 21 by 9. Then you add up the top block (18 times 2 times 3) by the bottom one (7 by 21 by 9) to get 1431 (108+1323)

Just split them up


V=LWH

the small one has L=18, W=3, H=2
V=(18)(3)(2)=108 cm³

the large one has L=21, W=7 and H=9
V=(21)(7)(9)=1323 cm³

total is 1323cm³+108cm³=1431 cm³


the volume is 1431cm³

Bond [772]

Answer:

45.9

Step-by-step explanation:

Remember that the hundredths place value is the second number after the decimal point and to round that number has to be greater than five in order to round up.

1m=3.28084

3.28084\times14=45.93176

Hundredths place value = 3

Round:

3

=45.9

Hope this helps.

Through which angle of rotation does the image of a regular pentagon coincide with its preimage?
Svetach [21]
Answer: 72° or any muliple of it: 72°, 144°, 216°, 288°, 360°, ...

It can be either clockwise or counterclockwise.


Explanation:


Thi is because a regular pentagon has 5 congruent sides.

Then you determine the angle of rotation by dividing 360° (a complete turn) by the number of sides (5)

360° / 5 = 72°.

Then every 72° the segments of the image will overlap those of the preimage.
