Answer:

384 cm²

Step-by-step explanation:

Calculate the volume of metal in the block

V = 16 × 8 × 4 = 512 cm³

Then the volume of the cube = 512 cm³

That is

s³ = 512 ← s is length of side of cube, hence

s = \sqrt[3]{512} = 8 cm

The cube has 6 square faces, hence

surface area = 6 × 8² = 6 × 64 = 384 cm²

jekas [21]

Answer:

17

Step-by-step explanation:

As 2 phones are defective from a group of 98 that were checked, you can determine a percentage:

2/98= 2%

This indicates that 2% of the phones are likely to be defective and because of that you can find 2% of 850:

850*2%= 17

According to this, 17 phones are likely to be defective.
