What is the answer to 3x{5x[10+5(500-100)+399]}

scZoUnD [109]

500-100=400
5(400)=2000
399+10=409
2000+409+2409
5(2409)=12045
3(12045)-36135
so in total it's equal to 36135

Compute the following volume and surface area.

Vesnalui [34]

The surface area of rectangular solid is 208 square centimeter

The volume of rectangular solid is 192 cubic centimeter

<h3><u>Solution:</u></h3>

Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm

To find: surface area and volume of rectangular solid

Length = l = 4 cm

Width = w = 6 cm

Height = h = 8 cm

<h3><em><u>The formula to find the surface area of a rectangular prism is:</u></em></h3>

Surface Area = 2wl + 2lh + 2hw

where w is the width, the l is the length, and the h is the height.

$\text {surface area }=2(4 \times 6)+2(4 \times 8)+2(8 \times 6)\\\\\text {surface area } = 2(24) + 2(32) + 2(48)\\\\\text {surface area } = 48 + 64 + 96 = 208$

Thus the surface area of rectangular solid is 208 square centimeter

<h3><em><u>The formula for volume of rectangular solid is:</u></em></h3>

$Volume = Length \times Height \times Width$

$volume = 4 \times 6 \times 8 = 24 \times 8 = 192$

Thus the volume of rectangular solid is 192 cubic centimeter
