Roberto wants to build a wooden box with a volume of 8 cubic feet. How many different boxes, all with whole-number dimensions and a different-size base, will have a volume of 8 cubic feet? TEKS 5.6.B

Record your answer and fill in the bubbles on the grid.

Be sure to use the correct place value.

Answer:

It is given that

Roberto wants to build a wooden box with a volume of 8 cubic feet

Now,

We know that,

The factors of 8 are:

1, 2, 4, and 8

So,

The different dimensions for the volume of a wooden box built by Roberto is:

(1 × 8) × 1 = 8

(2 × 4) × 1 = 8

(1 × 4) × 2 = 8

(4 × 1) × 2 = 8

(1 × 1) × 8 = 8

(8 × 1) × 1 = 8
