- Trans: Tìm thể tích của hình chóp sao cho diện tích đáy là 100cm2 và chiều cao là 9cm.

\(S=\dfrac{1}{3}.h.S_{\text{Đáy}}=\dfrac{1}{3}.9.100=300(cm^3)\)

Vậy \(S=300cm^3\)

The volume of the pyramid:

\(\dfrac{1}{3}.100.9=300\left(cm^3\right)\)

Gọi cạnh hình lập phương là \(a\left(cm\right)\)thể tích hình lập phương là \(V\left(cm^3\right)\)

Ta có: \(V=a^3\Rightarrow8x^3+60x^2+150x+125=a^3\)

\(\Rightarrow a^3=\left(2x+5\right)^3\Rightarrow a=2x+5\left(cm\right)\).

\(\Rightarrow\) Diện tích toàn phần của hình lập phương là: \(6a^2=6\left(2x+5\right)^2\left(cm^2\right)\).

\(\Rightarrow\) Diện tích toàn phần của 3 hình lập phương như thế là: \(3.6\left(2x+5\right)^2=18\left(2x+5\right)^2\left(cm^2\right)\).
