A pyramid has a rectangular base with dimensions 12m by 8m. If its height is 14m, calculate the volume
322m3
448m3
632m2
840m2
คำอธิบาย
Volume of pyramid = \(\frac{1}{3}\) x base area x height
= \(\frac{1}{3} \times 12^4 \times 8 \times 14\)
= 4 x 8 x 14 = 448m3
= \(\frac{1}{3} \times 12^4 \times 8 \times 14\)
= 4 x 8 x 14 = 448m3
