Question

I bought a box of granola bars at the store that has a volume of 210 cubic centimeters

which of the following could be the dimensions of my box?

choose all answers that apply:

a. 15 cm long, 2 cm wide, 7 cm high
b. 14 cm long, 3 cm wide, 7 cm high
c. 7 cm long, 3 cm wide, 10 cm high

please help

Answer 1

It is a and c.

Explanation:

The length * width * height must equal 210.

15 * 2 * 7 = 30 * 7

= 210.

7 * 3 * 10 = 210.

= 210 cm^3.

I hope this helps.

Answer 2

a and c

Explanation:

The volume (V) of a cuboid is

V = lwh ( l is length, w is width, h is height )

The volume is given as 210 cm³

Check each of the dimensions given to determine which give the correct volume

a

V = 15 × 2 × 7 = 210 ← correct volume

b

V = 14 × 3 × 7 = 294 ← incorrect volume

c

V = 7 × 3 × 10 = 210 ← correct volume

Hence a and c could be the dimensions of the box
