================================

$\large \sf \underline{Direction:}$

================================

$\large \sf \underline{Answer:}$

$\qquad \qquad \huge \bold{2,400cm^(2) }$

================================

$\large \sf \underline{Solution:}$

$:\sf{SA=2(lw)+2(wh)+2(hl)}$

$:\sf{SA=2(20)(20)+2(20)(20)+2(20)(20)}$

$:\sf{SA=2(400)+2(400)+2(400)}$

$:\sf{SA=800+800+800}$

$\therefore\sf\underline{SA = \pmb{2,400cm^(2) }}$

Hence, the surface area that you are looking for is 2, 400cm².

Answer:

SA = 2,400 cm²

Explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

Substitute the values above and multiply:

SA = 2(lw) + 2(wh) + 2(hl)

SA = 2(20)(20) + 2(20)(20) + 2(20)(20)

SA = 2(400) + 2(400) + 2(400)

SA = 800 + 800 + 800

SA = 2,400 cm²

Final answer: 2,400 cm²

Hope this helps!
