[6 × (4 − 2) + (21 × 2/3 + 1)] ÷ 3²
If you can, please explain.

3

Step-by-step explanation:

[6 x (4 - 2) + (21 x 2/3 + 1)] ÷ 3^2

[6 x 2 + (21 x 2/3 + 1)] ÷ 3^2

21 x 2/3 = 42/3 = 14

[6 x 2 + (14 + 1)] ÷ 3^2

[6 x 2 + 15] ÷ 3^2

[12 + 15] ÷ 3^2

27 ÷ 3^2

3 x 3 = 9

27 ÷ 9 = 3

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
