6.2 yd
krok68 [10]

Answer:

60.26yd³

Step-by-step explanation:

Since we are not given the diagram, let us assume that;

Length of the base = 5.4yd

Height of the pyramid = 6.2yd

volume of the square pyramid = BH/3

B is the base area = L^2

B = 5.4²

B = 29.16yd²

H = 6.2yd

Get the volume

volume of the square pyramid = 29.16*6.2/3

volume of the square pyramid = 180.792/3

volume of the square pyramid = 60.26yd³

Hence the volume of the square pyramid to nearest hundredth is 60.26yd³
