A rectangular prism is made of 81 unit cubes. The prism is 9 unit cubes long.
dimaraw [331]

Answer:

A width: 3 unit cubes

height 3 unit cubes

Step-by-step explanation:

Volume of rectangular prism = 81 unit cubes

l = Length of rectangular prism = 9 unit cubes

w = Width of rectangular prism

h = Height of rectangular prism

Volume of a rectangular prism is given by

V=lwh\\\Rightarrow 81=9wh\\\Rightarrow wh=\dfrac{81}{9}\\\Rightarrow wh=9

The product of width and height must be 9 so from the options this is only possible when width and height both are 3 units.

So, the width is 3 unit cubes and the height is 3 unit cubes.

1. Identify and EXPLAIN the ERROR
Anit [1.1K]

This might be a trick question. I did the problem and got the exact same answer. I got 31 x + 0.5. If there's anything they did wrong maybe its because they didn't put a zero before 5 so 5 could become a decimal?
