Question

Sebuah balok berukuran panjang 3 cm, lebar 4 cm, dan panjang diagonal ruang 13 cm. Volume balok adalah

Answer 1

Answer:

$V=144\ cm^3$

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

$h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm$

#The volume of the beam can then be calculated as:

$V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3$

Hence, the beam's volume is $144\ cm^3$
