Answer:
v = 124 cm³
Step-by-step explanation:
The figure shown is a composite figure. You can compartmentalize this figure into two separate figures to facilitate calculating the volume. I will section the figure into a cube and a rectangular prism. In a cube, the sides are congruent. So,
v = a³
v = 4³
v = 64
Now, for the rectangular prism.
v = l · w · h
v = 10 · 3 · 2
v = 60
Now, for the total collective volume, simply add up the volumes of the independent shapes.
64 + 60 = 124 cm³
<em>Answer:</em>
<em>√81 = 9 </em>
<em>Step-by-step explanation:</em>
<em>√(32+42) = √74</em>
<em>√64 < √74 < √81</em>
<em> +10 ⇔ +7</em>
<em>the nearest whole number √81 = 9 </em>
(Base 1 + base 2) divided by 2 times height
