Because 2 is the greatest integer not greater than 2.4 and –3 is the greatest integer not greater than –2.4. Because 2.4 rounds to 2, and –2.4 rounds to –3. Because 2.4 is positive and –2.4 is negative, they are rounded in different ways. Because 2.4 and –2.4 are both divisible by 2 and by 3, the value of each expression can be ±2 or ±3.

Srekar needs to increase the size of the prism below by 2 inches on each side. the original prism has a length of 3, a depth of 2, and a height of 1.  which statements about the new prism are true? check all that apply.the new prism will have a length of 5 because mr023-2.jpg.length=3+2=5. this statement applies.the new prism will have a depth of 4 because mr023-3.jpg.depth=2+2=4. this statement applies.the new prism will have a height of 2 because mr023-4.jpg.height=1+2=3. this statement doesn't apply.the volume will increase by 6 because mr023-5.jpg and each of the 3 dimensions is increased by 2.this statement doesn't applyinitial volume=3*2*1=6 cubic inchesfinal volume=5*4*3=60 cubic inchesthe volume will increase by 60-6=54srekar could increase the volume by the same amount by just adding 6 to the height instead of 2 to each sidefinal volume=3*2*(1+6)=3*2*7=42this statement doesn't applythe volume of the new prism will be mr023-6.jpg because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each.the volume of the new prism will be 60 cubic inchesthis statement applies
