The volume of each block is

                           (10in x 7 in x 5 in) = 350 inches³ .

With  14,000 in³  of material, they could make

                       (14,000 in³) / (350 in³/block) = 40 blocks .

Answer: There are 40 bricks they make.

Step-by-step explanation:

Since we have given that

Length of each brick = 10 inches

Width of each brick = 7 inches

Height of each brick = 5 inches

So, Volume of each brick = Length × Breadth × Height

[tex]Volume=10\times 7\times 5\\\\Volume=350\ in^3[/tex]

Since, If they used 14000 in³ of concrete.

So, Number of bricks is given by

[tex]\dfrac{\text{Volume of concrete}}{\text{Volume of brick}}\\\\\\=\dfrac{14000}{350}\\\\\\=40[/tex]

Hence, there are 40 bricks they make.
