Plz help me out, I only have a minute to submit this..
Pilar built a tower by stacking identical layers on top of each other. If her tower used a total of 312 blocks and if the bottom layer has 13 blocks, how tall is her tower? Explain how you know.

The height of the tower = 24 units.

Explanation:

In the question above, we are given the following variables.

The total number of blocks used = 312 blocks

The bottom layer( base of the tower) = 13 blocks

We are to find how tall the tower is = height of the tower = unknown.

The total number of blocks used = Volume of the tower = 312 cubic units(blocks)

Area of the base = number of the blocks used in the bottoms layer = 13 square units( block).

Because blocks are used, we assume that this is a Rectangular based prism

The Volume of a Rectangular based prism = Area of the base × h

312 = 13 × h

h = 312 cubic units ÷ 13 square units.

h = 24 units.

There fore, the height of the tower = 24 units

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
