10 Short answers and 20 multiple choice. Hope this helps. :)
Answer:
See Below
Step-by-step explanation:
To get volume of cuboid, we multiply the 3 dimensions.
<u>Volume of Box</u> = 28 * 15 * 20 = 8400
<u>Volume of 1 disc case</u> = 1.5 * 14.2 * 19 = 404.7
<u>Volume of 17 disc cases</u> = 17 * 404.7 = 6879.9
Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = 
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
Answer:
21, 42, 63, 84.
Step-by-step explanation:
The cards with a star and a circle must be multiples of 3 and 7.
So these must also be multiples of 21:
These are 21, 42, 63 and 84.
