You are stacking wooden blocks (cubes) whose sides are all 1 1/4 inches how many blocks do you need to stack or build a block tower that is 7 1/2 inches tall

You need to stack 6 blocks to build the block tower.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).

Mathematically speaking:

7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes

You need to stack 6 blocks to build the block tower.

Feel free to ask for more if needed or if you did not understand something.

the anwser is d) 75°

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
