Penjelasan dengan langkah-langkah:
1. LP balok=2(pxl) +(pxt) +(lxt)
=2(32x15) +(32x8) +(15x8)
=2(480+256+120)
=2x856
=1.712 cm³
2.L=6xrxr
=6x35x35
=7.350 cm³
3.LP kubus = 6xsxs
21.600 = 6xsxs
s² = 21.600/6
= 3.600
s = √3.600
= 60 cm
4. LP kubus = 6xsxs
= 6x24x24
= 3.456 cm³
5. LP balok = 2(pxl) +(pxt) +(lxt)
= 2(26x18) +(26x13) +(18x3)
= 2(468+338+234)
= 2x1.040
= 2.080 cm³
