Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V = 
area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V = × 16 × 4 = 
= 21 ft³
1/4= 0.25
2/4= 1/2 = 0.5
0.25 x 0.5 = 0.125
0.125 = 1/8
Answer:
Width Length
5 8.7
7.9 11.6
9 12.7
11.3 15.0
13 16.7
Step-by-step explanation:
If they gave you the width, you add 3.7 to get the length.
If they gave you the length, you subtract 3.7 to get the width.
Let the bigger no. be X and the smaller no. be Y
X-Y=48
7-3=4
48÷4=12
X=12×7=84
Y=12×3=36
90 × 7 = 630 , it's not hard, it's easy
