Answer:
24 cm²
Step-by-step explanation:
You can show your sister how to use the formula for the area of a triangle.
The base dimension is substituted for the letter b, the height is substituted for the letter h, and then the arithmetic is carried out.
A = 1/2bh
A = (1/2)(12)(4) = (6)(4) = 24 . . . . square centimeters
Answer:
4 times as tall.
Step-by-step explanation:
Volume of the box with the smaller base = 2*2* h1 = 4h1 where h1 is its height.
Similarly the volume of the larger base box = 4*4 * h2 = 16h2 with height h2.
So the ratio of their volumes is 16h2 / 4h1 = 4h2 / h1.
Now the volumes are equal so 4h2 = h1.
Therefore h2 = h1/4 so h1 = 4h2.
The box with the smaller base is 4 times as tall as the other box.
