Answer:
1.2cm³
Explanation:
The question is incomplete. Here is the complete question.
"What is the difference of the volumes of the two oblique pyramids, both of which have square bases? Round the volumes to the nearest tenth of a centimeter.
2 oblique pyramids with square bases are shown. Pyramid A is a base edge length of 2.6 centimeters and a height of 2 centimeters. Pyramid B has a base edge length of 2 centimeters and a height of 2.5 centimeters."
Formula for calculating the volume of a pyramid = 1/3 × base area × height.
Since the pyramids have square bases, the base area will be the area of a square.
Area of a square = L²
PYRAMID A
Height = 2cm
Base area = 2.6×2.6 (length of the square is 2.6cm)
Base area = 6.76cm²
Volume = 1/3 × 2 × 6.76
Volume = 4.5cm³
PYRAMID B
Height = 2.5cm
Base area = 2×2 (length of a side is 2cm)
Base area = 4cm²
Volume = 1/3×2.5×4
Volume = 3.3cm³
Difference between the volume of both oblique pyramid = 4.5cm³-3.3cm³
= 1.2cm³
Difference in volume to nearest tenth is 1.2cm³
