Surface area is the area of every surface. Since this is a cube, we can find the surface area by multiplying the area of one of the faces by six. The area of any face is 64 square inches. So, the surface area is 384 square inches

**Answer:**

77 + n ≥ 100

**Step-by-step explanation:**

We know that adding two numbers (77 and n) must be equal to or greater than (≥) 100.

So we can write the equation like:

77 + n ≥ 100

**Answer:**

30 red beads

**Step-by-step explanation:**

The data collected by Jake shows that there are 1.5 times as many red beads as yellow beads.

Red beads + Yellow beads = 50 beads total:

1.5n + n = 50, where n represents the number of yellow beads.

Simplifying this equation, we get 2.5n = 50, so that n = 20.

If there are 20 yellow beads, then there must be (50 - 20) red beads, or

30 red beads.
