Jerry built a 2 inch cube to hold his marble collection. He wants to build a cube with a volume 8 times larger. How much will each edge measure?

Answers

Answer:

4 inches

Step-by-step explanation:

Jerry built a 2 inch cube to hold his marble collection.

Volume of this cube = 2³ = 8 cubic inches

He wants to build a cube with a volume 8 times larger.

Hence: 8 × 8 in³ = 64 in³

The measurement of each edge is calculated as:

√64 in³ = 4 inches

Answers

Answer: incorrect,

6r=72

Divide both sides by 6

R=12

Answer:

Brooke's solution is incorrect.

She has to DIVIDE 6 on BOTH sides, not subtract 6 from both sides.

6r = 72

6r/6 = 72/6

r = 12

Step-by-step explanation:

The formula used to solve for leg a of a right triangle is a= sqrt(c^2-b^2). This is replaced by sqrt(6^2-5^2) for your equation. If you work this out, it equals about 3.32, and you have to round it to the nearest tenth, so the answer is 3.3 m.
