Answer:
ummmm its 1.68 am i missing something
Step-by-step explanation:
Answer: the answer is
Step-by-step explanation:
4 teaspoons because there are 3 teaspoons in 1 tablespoon
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
From the prism:
Perimeter P = 2(w + l)
40 = 2(w + l)
w + l = 20 (1)
Also:
Base area (B) = wl
100 = wl (2)
from equation 1 and 2:
w = 10, l = 10
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
