Answer:
6,656 square meters
Step-by-step explanation:
Surface area of triangular pyramid = bh + L(S1 + S2 + S3)
Where,
b = 48 m
h = 32 m
L = 40 m
S1 = 40 m
S2 = 40 m
S3 = 48 m
Plug in the values
Surface area = 48*32 + 40(40 + 40 + 48)
= 1,536 + 5,120
= 6,656 m²
If Ava waters her lemon tree 12 times, then she has used 10.667 gallons of water.
<u>Solution:</u>
Given that , Ava uses gallons of water every time she waters her lemon tree.
If she waters her lemon tree 12 times, we have to find how much water will she use
Total water used = water used for 1 time number of time water used for plants
Here water used for one time =
Number of time watered = 12
Hence, Ava used 10.667 gallons of water.
