Jimmy's cedar trunk is in the shape of a rectangular prism and has a volume of 3/4 cubic yard. How many cubic blocks with a side
gizmo_the_mogwai [7]

Answer: 6 blocks

Step-by-step explanation:

Given

Volume of the rectangular prism is V=\dfrac{3}{4}\ yd^3

Length of the cubic block is a=\dfrac{1}{2}\ yd

Volume of each cubic block is

\Rightarrow V_o=\left (\dfrac{1}{2}\right)^3\\\\\Rightarrow V_o=\dfrac{1}{8}\ yd^3

Suppose, n blocks are required to measure the volume of Prism

\Rightarrow V=nV_o\\\\\Rightarrow \dfrac{3}{4}=n\cdot \dfrac{1}{8}\\\\\Rightarrow n=\dfrac{3\times 8}{4}\\\\\Rightarrow n=6\ \text{blocks}

Thus, 6 blocks are required to measure the volume of prism.

To solve -3 = -19 + d/5, what steps would you use?
Phantasy [73]

Answer:

1)Add 19

2)Multiply by 5

Step-by-step explanation:

-3=-19+\frac{d}{5}

Adding 19 to both sides.

-3+19=-19+19+\frac{d}{5}\\\\16=\frac{d}{5}

Multiplying 5 to both sides.

16\times5=\frac{d}{5}\times 5\\80=d\\\\

∴d=80
