The sum of the measures of angle 4,7, and _____ is equal to 180

1 answer:

6 0

7 I think because if you would put a zero behind the 4 and 7 and add them together it will be 110 and all that's left if u subtract them from 180 is 70 (7)

How tall is a stack of cube shaped blocks whose volumes are 375 cube inches, 648 cube inches, and 1029 cube inches?

djverab [1.8K]

Answer:

L = 25.959 inches

Step-by-step explanation:

Volume of first cube = 375 inch³

Volume of second cube = 648 inch³

Volume of third cube = 1029 inch³

We need to find the length of the stack of the cube shaped block.

We know that,

The volume of a cube = a³ (a is side of a cube)

$a_1=\sqrt[3]{375} \\\\=7.211\ \text{inches}$

$a_2=\sqrt[3]{648 } \\\\=8.653\ \text{inches}$

$a_3=\sqrt[3]{1029} \\\\=10.095\ \text{inches}$

Hence, the total length of the stack is :

L = 7.211 + 8.653 + 10.095

= 25.959 inches

Hence, this is the required solution.
