Find the volume of the solid- 2cm, 4.5cm, 3.5cm

1 answer:

5 0

For the volume of this solid, you’re first going to find the area of the front triangle. so base x height divided by 2. for this it would just be 4.5. then multiply that by the side length. so 4.5 x 3.5, which would be 15.75. so your answer would be 15.75 cubic centimeters

Then simplfy
9x+5=9x+8

Estimate 4,377divied by 8

Stella [2.4K]

When you estimate, you round the numbers up or down. In this case, I'll round 4,377 down to 4,000, because 8 divides nicely into that number. 4,000/8 = 500.
You could estimate it to be about 500.
Hope that helped you.
(You can round your own numbers if you would like, but remember that rounding should make it easier for you to solve!)
